v4 is one mature, accumulated framework; npmap5 is a still-in-progress
rewrite split into small, independently-versioned (mostly pre-1.0)
plugins, several of which aren't merged yet. Worth knowing so we don't
assume v5 already has everything v4 does.
Noted for completeness in docs/nps-resources.adoc — both proprietary/
licensed fonts, unlike the SIL OFL Noto Sans already vendored, so not
adoptable. The editorial style guide is NPS's own writing/terminology
conventions, not a design or code resource, included only since it was
shared alongside the typography notes.
A reference doc (docs/nps-resources.adoc) covering everything looked at
while pulling icons/controls/theme colors from NPS's mapping ecosystem:
what's actually in use (symbol-library, home-button, the Park Tiles-inspired
offline palette), what was considered and deliberately skipped (svg-icons,
markdown-handlebars, the unmerged overview/carto/wms branches) and why, the
Park Tiles cartography research (Harpers Ferry Center lineage, the four
style variants, why the actual tile service is off-limits via Mapbox
Atlas licensing, the public style JSON and Mapbox Studio style IDs found),
and the still-open upstream PR revising artwork for three icons we use.
Worth having as a knowledge base rather than re-deriving any of this from
scratch next time — NPS's tooling has repeatedly turned out to be a better
source than building something from nothing.
