The sticker on every poster card was hard-wired to "Show on map". A wall with
no map beside it (a gallery of poster templates) needs the same card with a
different action, and a fork of the card would drift from the wall.
headerAction null (the default) renders the existing toggle unchanged: the
same markup, aria-pressed, the is-last highlight and the window event, so
every current wall is untouched. { labelKey, ariaKey } renders a plain button
labelled from those keys that emits 'header-action' with the item and
dispatches no window event.
check:poster-wall-header-action (gates:pre) mounts the real PosterWall
headlessly on a recording renderer and calls the sticker's onClick in both
modes. Four mutants fail it: no seam, a new branch that also dispatches, a
default that emits, and aria-pressed on the new branch.

library/ (@map) — the shared map template
The other half of the architecture (see ../plugin-designs/README.md):
every map in plugin-designs/<your-map>/ composes the reusable, parameterized pieces that live here.
Fix something here and every map benefits on the next build; break something here and every map
breaks — read components/WARNING.md before touching shared pieces.
| Folder | What lives there |
|---|---|
ProfileLoader.vue |
The root of every bundle: parses profile-config, loads the profile, provides the stores + config |
components/ |
Shared UI — map, legends, controls, popup (PeopleGroupDetail), tables, charts, hints (README) |
composables/ |
Shared logic — map engine (useMapInstance), provider switch, shadow-DOM styles, theming |
stores/ |
Per-instance Pinia stores (ui / map / data) — provided by ProfileLoader, injected by children |
api/ |
Data-source registry (sources.json) + fetch layer — the JAMstack runtime wiring |
colors/ |
Color sets maps opt into via profile-config.colorSet |
i18n/ |
The shared string catalogs (all maps speak the same languages) |
data/ |
Small shared datasets baked at build time (big served data lives in ../data/) |
constants/ |
Shared constants |
scripts/ |
Maintainer pipelines (posters, research) — not part of any bundle |
The rule of thumb (same as WARNING.md): custom code in your app-profile, reusable code here — and things only move from the first to the second once they've earned it.
