The old link only ever surfaced one nearby article at a time, buried
in whatever POI's popup you happened to open, and only for uploaded
files with a category. Replaced it with a standalone "Wikipedia"
toggle under the renamed "Tracks & Points" panel: enabling it adds a
live map layer that refetches GET /api/kiwix/nearby on every pan/zoom
and plots every nearby article as its own point.
kiwix-serve's own geo search never echoes back a result's coordinates
(confirmed live against the real production ZIM, both its HTML and
?format=xml output) — it only filters by distance from a point. So
Maptool::Kiwix.nearby fetches each matching article's own page too and
reads its <meta name="geo.position"> tag, which every geotagged
Wikipedia article carries. Tried parallelizing those per-article
fetches with threads first; measured no improvement against the real
ZIM (kiwix-serve appears to serialize requests regardless), so it
stayed sequential — ~1.6s for a 30-result page, fine for a
refetch-on-pan-end layer.
Clicking a point opens a small popup linking to the article (proxied
through the existing /kiwix/* passthrough). New WIKI_ICON (NPS's
bookstore-22.svg) marks these, kept out of POI_ICONS since that set
doubles as notes.js's icon-picker option list and this fixed-glyph
layer has no per-feature category to key off of.
A failed run showed "Failed — see server log" regardless of why —
misleading, since a Plugins::RunError never actually reaches any log
(app.rb turns it straight into a 502 JSON response). Found this the
hard way debugging the p4n2gpx plugin, having to SSH in and reproduce
the run by hand each time just to see why it failed. Now shows the
response's actual error message (e.g. "plugin exited with status 1"),
wrapping instead of overflowing the flyout for a longer one.
A plugin is a directory under plugins/ with a plugin.json manifest
({"label": "...", "command": "./run.sh"}) plus a script that reads
--south/--west/--north/--east and prints a GeoJSON FeatureCollection
to stdout (lib/maptool/plugins.rb) — that's the entire interface a
plugin needs to know about this app. The sidebar's new import icon
(logged in only, GET /api/plugins + POST /api/plugins/:name/run) lists
whatever's found and runs one for the current map viewport, saving its
output as a new .geojson file the same way an upload would be.
The point: a scraper for a site whose ToS forbids that (Park4Night,
iOverlander, Freecampsites) doesn't need to live in this public repo
to work here — its own directory just goes under plugins/ locally and
is never git add'ed, no special-casing needed anywhere.
plugins/overpass-pois wraps the existing rake overpass:pois query as
the first, in-repo, reference example of the contract.
Also fills in four modules (auth.js, locate.js, measure.js, notes.js)
missing from layout.erb's cache-busting importmap alongside adding
plugins.js's own entry — a pre-existing gap that meant they could keep
serving a stale cached copy across a deploy despite the importmap
existing specifically to prevent that.
- "Nearby on Wikipedia" linked to KIWIX_URL, a Docker-internal hostname
(http://kiwix:8080) no real browser can resolve. Split it: KIWIX_URL
stays server-side-only for the reachability check, and the link
itself is built from KIWIX_PUBLIC_PORT (kiwix-serve's newly
published host port) plus whatever host the visitor already used to
reach maptool — works regardless of which hostname/IP that is.
- The Save button went white on hover in GTK-themed Chrome: the
browser's native button skin was painting over the custom
background because appearance wasn't reset.
- The map preview marker for a pending note always showed a plain red
pin no matter which icon was picked in the form. NoteSaveForm now
reports icon changes via onIconChange so NotesControl can update the
marker's glyph live.
- Saving a note (or a Measure "Save as note") left the new/grown
.geojson file unchecked and invisible until manually toggled on.
notifyGpxStoreChanged now carries the affected path so
GpxPanelControl auto-shows it.
lib/maptool/kiwix.rb: a small reachability check for an external
kiwix-serve instance. GET /api/kiwix reports it (same optional-
integration pattern as offline-tiles/terrain-tiles); the frontend
adds a "Nearby on Wikipedia" link to a point's popup pointing straight
at kiwix-serve's own geo search (GET /search?latitude=&longitude=
&distance=, confirmed from libkiwix's actual source rather than
guessed) — linked to directly, not proxied/embedded, since it already
has a full search UI of its own.
docker-compose.yaml: new `kiwix` service (ghcr.io/kiwix/kiwix-serve)
on the default network, KIWIX_URL wired to reach it by service name.
The ZIM itself isn't part of the repo (large, self-contained archive)
— data/kiwix/ gitignored same as the *.pmtiles files, setup steps in
docs/development.adoc.
No kiwix-serve/ZIM available here to test end-to-end — verified the
app side against a stand-in local HTTP server (GET /api/kiwix flips
available correctly) and confirmed the generated popup link matches
the real geo-search query shape. docker-compose.yaml validated with
`docker-compose config`. Full test suite: 118 runs, 0 failures.
- The clicked location now stays marked (a plain maplibre-gl Marker,
removed on save/cancel/deactivate) while the note form is open —
before, nothing on the map showed where the pending note would land.
- POI_ICONS gains a dozen more symbols (water, dump station, toilets,
playground, viewpoint, swimming, fishing, climbing, hiking, …) via
Object.assign after PARK4NIGHT_TAGS' own icon constants are declared
(they're below POI_ICONS in the file, so the literal itself can't
reference them directly) — reused as real marker-badge glyphs, not
just PARK4NIGHT_TAGS' inline description-tag icons. NoteSaveForm
gets a picker grid for these, shown only for a Point note (a
Measure-drawn line/polygon has no one spot for a badge).
- Fixed: .notes-panel__save's blue background was losing to
.notes-panel__actions button's gray — same class-vs-class+element
specificity trap .gpx-panel__action[hidden] already has a comment
about elsewhere in this file. The button was never actually blue.
Verified live (properly simulating a logged-in session this time, via
Page.addScriptToEvaluateOnNewDocument rather than a post-load DOM
poke, since NotesControl's mount decision happens once, synchronously,
at page load): marker appears and clears correctly, 19 icons + "none"
render and select, Save renders #1a5fb4. Full suite: 115 runs, 0
failures.
Both NoteSaveForm (create) and the popup's inline Edit form now have
a title input (-> properties.name, shown in the black header, same as
every other waypoint popup) and a separate body textarea (->
properties.description) for more detail than a single line.
New formatNoteBody renders that body with a small self-rolled
markdown subset — **bold**, *italic*, auto-linked URLs (reusing the
existing linkify), newlines to <br> — deliberately a new function, not
a change to formatDescription: that one renders uploaded GPX/park4night
content, which is untrusted, and docs/nps-resources.adoc already has a
specific call not to add markdown rendering to that path. A note's
body is written by the logged-in viewer themselves, not uploaded, so
that concern doesn't apply here — the escape-then-selectively-markup
order (linkify first, since it does its own escaping, then wrap
already-escaped text in real <strong>/<em> tags) keeps it safe either
way.
Verified live: title renders in the popup header, **bold**/*italic*/
a URL in the body all render correctly. Full test suite: 115 runs, 0
failures (unaffected — description is just another property, not
something the backend routes inspect).
Adding a note (either tool) always ended in a 401 for a logged-out
viewer — the write-only affordance just wasn't hidden yet, unlike
GpxPanelControl's own upload/new-folder buttons, which already are.
NotesControl isn't added to the map at all when logged out (its whole
purpose is writing); MeasureControl's "Save as note" button is hidden
but the tool itself stays usable for plain measuring either way.
Measure already draws distance lines and area polygons by hand — a
second click-to-draw UI in the notes tool (Point/Area mode, from the
previous commit) duplicated that. Replaced it with a "Save as note"
button on the Measure panel that saves whatever shape is currently
drawn there; NotesControl goes back to being just a one-click point
pin. Both share a single NoteSaveForm (notes.js) for the note-text +
target-layer-file UI instead of two copies of it.
gpx.js: the "lines" source now also renders a note-flagged LineString
(dashed, popup-on-click) alongside the Polygon fill/outline from
before — the plain track-line layer excludes category:"Note" features
so a saved distance note doesn't also get the track hover-summary/
profile-panel treatment.
Notes are now individually editable/deletable from their own popup
(logged-in only): Edit swaps the popup content for an inline
textarea, Delete confirms and removes. Both target the feature by a
new client-generated properties.id rather than array position (new
GpxStore#update_feature/#delete_feature, PUT/DELETE /api/gpx/notes),
since neither array index nor the note's own text (the thing being
edited) is a stable identifier.
Verified live: Measure's Save button (disabled/enabled state, saves
the exact on-screen shape), the popup's Edit/Delete buttons and inline
edit form. Full test suite: 115 runs, 0 failures (new coverage for
update_feature/delete_feature and the PUT/DELETE routes).
notes.js: Point/Area mode toggle mirroring measure.js's UX — Area
mode accumulates clicked vertices with a live dashed-preview polygon
(own small preview source/layers), a Finish button once 3+ corners
are placed, then the same save form as Point mode.
gpx.js's _addLayers now also renders Polygon features from a file's
"lines" source (fill + outline, filtered by geometry-type — the
existing line layer already only draws LineString, so this is just
two more layers on the same source, not a new bucket) with
popup-on-click like a waypoint, not the track line's hover-summary/
profile-panel behavior. Without this a saved polygon wouldn't have
rendered back on reload.
Fixed along the way: .notes-panel__form/.notes-panel__modes both set
their own `display`, which silently wins over the browser's default
`[hidden] { display: none }` (author styles always beat user-agent
ones) — same gotcha .gpx-panel__action[hidden] already has a comment
about. The form was never actually invisible before being opened.
Verified live: real polygon file (fill/outline render, click ->
popup) and the full Area-mode draw flow (mode switch, live preview,
Finish, form) via headless Chrome. Full test suite: 104 runs, 0
failures — one new backend test confirms a Polygon feature round-
trips through POST /api/gpx/notes.
Known gap (noted in TODO.adoc): the category filter matrix only
re-slices the points source, so toggling "Note" off hides point notes
but not polygon ones.
New map-corner "Add note" control (public/js/notes.js), mirroring
measure.js's click-to-place UX. Click the map, write a short note,
pick an existing .geojson layer file or name a new one — saved via a
new GpxStore#append_feature (grows the target file in place, unlike
save()'s always-disambiguate-the-filename behavior) through a new
POST /api/gpx/notes route.
No new rendering path: a note is just another point in a .geojson
file the Tracks panel's tree already lists, checkboxes, and pops up —
visibility toggling ("layers") comes for free from that existing
machinery, per-file, with no changes needed there.
Points only for now — a polygon mode would need gpx.js's point/line
split taught a third Polygon bucket first, or a saved polygon
wouldn't render back on reload (see TODO.adoc).
Covered by new tests: GpxStore#append_feature (create/append/missing-
path/filename-safety) and the /api/gpx/notes route (auth gate, create,
append, malformed/missing-geometry rejection, 404 on a missing
target). Full suite: 97 runs, 0 failures.
Radar flyout now also shows a 3-day Open-Meteo forecast (free, no API
key) for the map's current center. Radar frames and the forecast fetch
independently — one being unreachable doesn't hide the other. The last
successful forecast is cached in localStorage and shown (with a
"cached from" note) when the live fetch fails, so there's still
something useful once actually offline.
Radar tile images themselves aren't cached — that needs a Service
Worker, left as a separate follow-up (see TODO.adoc).
Small green/gray indicator reusing the existing /api/offline-tiles
check, showing at a glance whether this server has offline map data.
Closes out the top banner TODO item — DEM elevation and a hamburger
menu are intentionally left out (no DEM layer yet, and the sidebar
isn't mobile-collapsed).
Legend items are now toggle buttons (icon grid, not a color-swatch
list) that hide/show that category's waypoints on the map. Filtering
re-slices each file's source data rather than using a layer filter,
since MapLibre clusters a GeoJSON source's full data regardless of
what a layer filter hides.
Black topbar banner with live map-center coordinates, a black header
(with NPS pictogram) on waypoint popups, offline basemap wood/park
colors unified with the online Liberty green, and the sidebar grouped
into the planned Explorer / Offline hub / Navigation menu sections.
Ended sessions past the ~24h Garmin appears to keep a live-track page
around for get verified once at app startup and, once confirmed dead,
flagged so the panel greys them out instead of only failing after a
click. Already-flagged sessions are skipped on later startups so this
doesn't keep re-hitting Garmin for the same dead session.
.gpx-panel__action's own "display: flex" outranks the browser's
default "[hidden] { display: none }" -- same specificity, but an
author stylesheet rule always beats a user-agent one -- so setting
.hidden = true on these (GpxPanelControl#mount) never had any visual
effect. The per-file row icons (delete/download) were unaffected by
this since they're conditionally never added to the DOM at all rather
than hidden after the fact, a different mechanism that doesn't hit
this bug.
Same class of bug as the earlier Distance/Area overlap fix. Swept the
rest of the app's [hidden]-manipulated elements for the same pattern
(a display override with no [hidden] counterpart) -- this was the
only other one.
Verified in a real browser: computed display is now "none", not just
the hidden attribute being set with no visual effect.
The file name doubling as a GeoJSON-only download link was easy to
miss as a link at all, and only ever covered half of what's actually
downloadable. One button next to delete now opens a small menu
(Original file / GeoJSON) instead -- costs a click when downloading
several files in a row, but both formats are reachable from one,
discoverable place. Only one menu open at a time, closed on any
outside click.
Verified in a real browser: opens with both items, closes on outside
click, no console errors.
The measure panel's mode buttons sit inside a maplibregl-ctrl-group
container (for the ruler button's own 29x29 sizing) — its global
"button" rule reaches them too, clipping "Distance"/"Area" into a
fixed 29px square with zero padding instead of sizing to fit the
text. Fixed by upping specificity (".measure-panel .measure-panel__mode")
rather than fighting the cascade with !important.
In distance mode, each segment between two clicked points now shows
its own length at its midpoint, not just the running total in the
panel — a symbol layer keyed off the existing source, filtered apart
from the vertex circles by a new "role" property.
Verified both in a real browser (panel no longer overlaps; two
638m segments rendered and labeled correctly summing to the panel's
1.28km total).
GpxStore#save converts eagerly, so "cached" is true for nearly every
file in the tree already — badging that was just noise. Flipped to
PENDING_ICON, shown only for the rare case: a .gpx/.fit dropped
straight into data/gpx/ on the filesystem, bypassing the app, and not
yet opened.
Also add an explicit download button next to delete (DOWNLOAD_ICON) —
the file name itself has been a download link since the last commit,
but isn't obviously clickable at a glance.
Once a .gpx/.fit is cached, the tree shows it under its converted name
("ride.gpx" -> "ride.gpx.geojson", matching the real cache file next
to it on disk) instead of still reading as un-converted -- the
GeoJSON is what's actually on the map from that point on, and the
original is never deleted, just not re-shown as itself. The name is
now a real link (GET /api/gpx/file/<path>?download=1) instead of
plain text, the only way to get that converted form out of the app.
Verified in a real browser that an <a> nested in a <label> claims its
own click rather than the label forwarding it to the checkbox, so
downloading and toggling visibility don't fight over the same click.
A newer p4n2gpx run (Ruby rewrite, ~/test/mapping/p4n2gpx) started
emitting one plain GPX <link href> per park4night listing photo,
which this app parsed but never displayed. Gpx.waypoint_photos
collects them into a photos property; the waypoint popup renders them
as a row of thumbnails above the description, each opening full-size
in a new tab. Absent on older exports and plain GPS waypoints, so the
row just doesn't render for those.
Home now fitBounds()s a country-wide bbox instead of resetting to
CENTER/ZOOM's Bratislava point, since Home resetting into the same
city you'd already be looking at wasn't useful.
The overview map is NPS's own overview plugin (npmap5-plugins, still
on an unmerged branch), vendored and converted from its UMD dist
build to a plain ES module. Patched one MapLibre API break found while
verifying it: the plugin reads map.transform (public in the MapLibre
~2.4 it targets) to relax the inset's polar pan limit; MapLibre 6 (this
app's vendored version) no longer exposes .transform at all, so it
threw on load. Guarded to skip that cosmetic adjustment when absent
instead.
A ruler button in the top-left control stack, matching NPS's own
Area/Distance ruler. Click to add vertices; distance sums haversine
segment lengths, area uses the spherical-excess polygon formula
(same one turf.js's area() uses) rather than a flat shoelace, since a
flat approximation drifts at park-boundary scale. SI units only
(m/km, m²/km²) — no imperial toggle.
Matches the small numbered square NPS keeps next to its own zoom
buttons — a passive display, not a button, so it's plain markup with
no click behavior.
NPMap4 has infoboxControl: a generic "click anything, show every raw
property" debug view, kept separate from a dataset's own curated popup.
Not portable code (Leaflet), but the concept is: Alt+click anywhere now
opens a popup listing every rendered feature at that point via
map.queryRenderedFeatures — base map OSM tags included, not just this
app's own GPX/FIT/radar layers — with a raw key/value table per feature.
No dedicated UI for it on purpose: a keyboard-modified click needs no
button, toggle state, or cursor change of its own, and it's fine for it to
coexist with a layer's own click handler firing on the same click (e.g. a
GPX waypoint's normal popup) since this is a power-user/debugging
affordance, not a replacement for those. Feature properties can come from
an uploaded GPX/FIT file (untrusted input) via this app's own layers, so
every value is escaped the same way gpx.js's popups already are.
The gray color from the previous commit landed on .gpx-popup__meta (the
whole row, label and value both) instead of just .gpx-popup__meta-label —
only the label was supposed to be muted, the value should read as normal
text same as the description above it.
While in there: Services/Activities were showing park4night's own raw,
comma-separated codes ("animaux, point_eau, wc_public"), which don't mean
anything to a reader on their own. PARK4NIGHT_TAGS (icons.js) maps the
codes p4n2gpx's exports actually use to a human label and, where the
National Park Service's icon set (already used for POI_ICONS) has a
reasonable match, a small icon — formatTags (gpx.js) renders each as an
icon+label tag instead of raw text. A code not in that table just falls
back to its own raw text, so nothing is ever hidden.
Secondary metadata, not something worth visually competing with the actual
description — dropped the bold label weight and colored the whole meta
block the same muted gray already used for category/time elsewhere in the
popup.
A park4night <desc> packs a free-text narrative and several lines of
structured data (address, rating, services, activities, the listing URL)
into one field, separated only by newlines. Rendered as a single paragraph
it read as a wall of run-together text — no visual hierarchy between the
actual description and what's really key-value metadata.
formatDescription now recognizes "Label: value" lines (Rating/Services/
Activities) and bare-URL lines, and gives each its own row instead of
burying them in the narrative paragraph: a bordered meta block with bold
labels, and an isolated link line. Anything that doesn't match — the real
narrative text, or a plain GPX file's <desc> with no such structure — stays
exactly as it rendered before, so this only adds structure, never removes
or reorders text.
A park4night/OsmAnd POI export (e.g. a p4n2gpx area export) tags every
waypoint with a category and a per-category color/icon in its <extensions>
block, all of which was previously thrown away — every waypoint rendered as
the same plain red dot, unreadable once a file has a few thousand of them.
Maptool::Gpx now captures category/color/icon (waypoint_style), matched by
namespace URI rather than local element name: a p4n2gpx file carries both
<osmand:icon> and <locus:icon> side by side, and REXML strips prefixes from
Element#name, so both report as just "icon" — matching on that alone was
silently picking the (useless) Locus drawable path instead of the OsmAnd
category key. Regression test added for this.
On the map: waypoints are colored by category (falling back to the plain
track color for anything uncategorized), a small hand-drawn icon set
(public/js/icons.js's POI_ICONS, rasterized to SDF sprites at runtime) draws
a glyph on top for the categories it covers, the points source is clustered
so a dense export collapses into count bubbles instead of a solid blob, and
a legend in the side panel lists whichever categories are currently visible.
Splitting each file's GeoJSON into a lines source and a points source
(rather than one mixed source with a geometry-type filter per layer) was
needed for clustering, since MapLibre's cluster support only understands a
source made entirely of points.
TrackStats.build_profile now also computes elapsed_secs per point
(relative to the first known timestamp), alongside the existing
cumulative distance. Point x-positions stay distance-based either
way — only the shared axis strip's 5 tick labels (and the tooltip)
switch between the two, so toggling is a cheap re-render rather than
rebuilding the charts. The toggle only appears when a track actually
has elapsed-time data to switch to.
Plain HTML overlays, not SVG text: the chart's viewBox scales width
and height independently (preserveAspectRatio="none", for a
responsive width at a fixed pixel height), so text drawn inside that
coordinate space would get stretched by the mismatched factor.
Track properties gain activity_type (FIT: sport enum from the
session/sport message, Garmin's own table; GPX: <trk><type> passed
through as-is) alongside the existing distance/elevation/duration.
Clicking a track line now opens a bottom panel with a chart per
metric the track actually has (elevation always; speed/cadence/heart
rate only when present — FIT's record fields or GPX's device
extensions). TrackStats.build_profile computes cumulative distance
the same way for both formats so they're directly comparable. One
pointermove listener drives a synchronized crosshair across every
chart, a single tooltip listing all series, and a map marker at the
hovered point's position — hovering the chart shows where on the
track that moment was.
A session's own end timestamp is absent until the activity is
actually stopped, so its presence/absence is the status signal — no
new data needed, just reading what was already there. Shown as a
badge next to the session in the list and in its map hover popup.
Fetching a session's track now also grabs its summary (name, activity
type, distance, duration) from the same page and stores it — sessions
the panel has actually shown replace their raw UUID with that summary,
and are kept indefinitely regardless of age. A session nobody ever
opened (no summary) is more likely test/dead data than something worth
keeping, so it's dropped automatically after 48h.
Clicking a LiveTrack session now fetches and draws its track (line +
latest position). Garmin's own API 403s any plain server-side request
(Cloudflare bot protection), so LiveTrackClient fetches the session
page instead and pulls the track out of the server-rendered data
embedded in it. The webhook now captures the session's token too,
since the id alone isn't enough to fetch anything.
A Gmail-watching Apps Script (documented in docs/deployment.adoc) posts
the session ID from each LiveTrack email to a new webhook, which stores
it in data/livetrack.json; a new sidebar panel lists what's been
received.
Upload/delete/move/create-folder now require logging in via Gitea
OAuth2 (only MAPTOOL_ALLOWED_GITEA_USER is granted write access);
reading stays public. Deploy secrets (session secret, OAuth2 client
credentials, allowed user) are written to .env from Gitea Actions
repo secrets on every deploy instead of living on the server by hand.
Also switch the container's bind address to "[::]" (dual-stack) so
the app is reachable over IPv6, not just IPv4.
Each tree entry now shows a small waypoint/track icon based on a
cheap substring check for <wpt>/<trk> (Maptool::Gpx.kinds) rather than
a full REXML parse, since re-parsing a several-thousand-waypoint file
on every tree fetch would make the panel noticeably slower to open.
Also fix a real drop-target bug: .gpx-tree had no flex:1, so a
short/empty tree left blank panel space below it that wasn't part of
the drag & drop target — dropping a file there silently did nothing.
Restructure the map controls from MapLibre corner buttons into a left
sidebar of icons with flyouts/panels (radar, GPX, GNSS), matching
OsmAnd's layout more closely:
- Base map and GPX selection are now full-height side panels docked
next to the sidebar (not small dropdown flyouts or a right-docked
panel), opening/closing exclusively via a small shared event bus
(panels.js) so only one is ever open at a time.
- The GPX panel's upload/new-folder controls are now icon buttons in
the header instead of an always-visible dropzone and form; dragging
a GPX file onto the tree, a specific folder, or straight onto the
map itself all upload it.
- New: Maptool::GpsdClient (lib/maptool/gpsd_client.rb) streams live
GNSS fixes from a local gpsd daemon over Server-Sent Events
(/api/gnss/stream) to a marker on the map (public/js/gnss.js) — one
background gpsd connection shared by every browser tab.
- The online map style (public/js/osmand-style.js) is now styled to
resemble OsmAnd's own rendering, applied to both the online and
offline (PMTiles) styles.
Also adds a GeolocateControl (browser geolocation) next to the zoom
controls.
Uploading is now drag & drop (or click to browse) instead of a form;
folders can be created any time, not just during upload; files can be
dragged onto a folder to move them, or dropped elsewhere in the tree
to move back to the top level; files and folders can be deleted. Both
drag sources (an OS file drag and dragging an existing tree entry)
land on the same drop targets, told apart by a custom drag payload
type versus the browser's own "Files" type.
Also sort folders before files in the tree (previously interleaved
alphabetically).
Upload GPX files into a folder hierarchy (traversal-safe path
resolution against the store root), browse them in a tree panel, and
toggle each one's waypoints/tracks on the map. Waypoints render as
clickable points showing name, description and time; bare URLs in the
description are turned into safe links. GPX layers survive switching
between the Online/Offline base map, same as the radar overlay.
Adds rexml as an explicit dependency — it moved to a bundled gem in
this Ruby version and isn't picked up by Bundler otherwise.
Replace Leaflet/raster tiles with MapLibre GL JS: an online OpenFreeMap
style and an offline style built from a local PMTiles archive via
pmtiles.js and protomaps-themes-base (no glyphs/labels offline by
design, see docs/architecture.adoc). Frontend libraries are vendored
locally rather than loaded from a CDN so the app keeps working with no
internet access.
Also add an animated RainViewer precipitation radar overlay (toggle,
play/pause, scrub slider), matching the default time window of the
weather-radar-card Home Assistant integration.
