Use the National Park typeface for the topbar wordmark
Self-hosted Bold woff2 only (the one weight .topbar__brand renders at)
under public/vendor/national-park-typeface/ — a router-carved-signage
display face for the "MAPTOOL" heading, matching the uppercase/
letter-spaced treatment it already had. Everything else stays on the
system font stack; this is a wordmark swap, not a body-text one.

docs/nps-resources.adoc/third-party-notices.adoc updated to record it.

Frontend libraries vendored under `public/vendor/` instead of loaded
from a CDN, so the app keeps working with no internet access. All are
BSD-3-Clause licensed.

Also vendored under `public/vendor/`, but not BSD-3-Clause like the
above — MIT-licensed per its own `package.json` (the monorepo's
top-level `LICENSE.md` separately places the whole repo in the public
domain as a work of the US government; either way, no attribution is
required):

| NPS Home Button (`home-button`)

| NPS Overview Map (`maplibre-gl-overview`)
| 5.0.1
| https://github.com/nationalparkservice/npmap5-plugins/tree/maplibre-gl-overview
|===
The overview map is vendored from an unmerged branch, not `main` (see
`docs/nps-resources.adoc`), and converted from its UMD dist build to a
plain ES module — no functional change except the module wrapper. It
was also patched for a MapLibre API break: it reads `map.transform`
(public in the MapLibre ~2.4 this plugin targets) to relax the
overview's polar pan limit, but MapLibre 6's `Map` no longer exposes
`.transform` at all — guarded to skip that (cosmetic) adjustment
instead of throwing when it's absent.
Offline map text labels need font glyphs too (see
`docs/architecture.adoc`), vendored under `public/vendor/fonts/` —
SIL Open Font License, not BSD-3-Clause like the above:

| Noto Sans Regular/Italic/Medium glyph PBFs (ranges `0-255`,
`256-511` only)
| https://github.com/protomaps/basemaps-assets[protomaps/basemaps-assets]
(`fonts/`, `OFL.txt` included alongside)
| National Park (Bold weight only, `.woff2`), topbar wordmark
(`.topbar__brand`, `public/css/style.css`) — see
`docs/nps-resources.adoc`
| https://nationalparktypeface.com[nationalparktypeface.com] (Ben
Hoepner, Andrea Herstowski, Jeremy Shellhorn / DO Studio) — "published
for free use under the SIL Open Font License" per the site; no
`OFL.txt` ships in its own download zips, unlike Noto Sans above

The online map style (not vendored, fetched at runtime when the
"Online" layer is selected) is
https://tiles.openfreemap.org/styles/liberty[OpenFreeMap "liberty"],
built from https://www.openstreetmap.org[OpenStreetMap] data.
To update a vendored library: download its package (e.g.
`npm pack <name>@<version>`), replace the corresponding files under
`public/vendor/<name>/`, and update the version in this file.
