- ONE REGISTRY PER PAGE. Every bundle inlines its own copy of posterTypes.js, and <dxm-poster-section> is
defined by whichever bundle loads first, so with a module-level Map that element saw only its own bundle's
types: type="upg100-list" rendered "none" when the country-posters bundle had defined it. The registry now
lives on the page (globalThis.__DXM_POSTER_TYPES__, created once): every copy registers into it and reads
from it; a name registered twice keeps the first (a dev warning; the built-in country is silent); every
registration is announced on window (dxm-poster-type-registered), and PosterSectionView looks again when
its type arrives after it asked.
- COLUMNS (carried from the Poster Sections plugin PR so the element's library lands once): columns="1".."5"
maps to profile-config.columns and to PosterWall's existing columns prop; absent or out of range is
today's default, and a reader's saved per-row choice still wins.
- check:poster-type-registry (gates:pre; self-test in gates:post): two independent copies of the module side
by side, as two bundles on one page; a type registered through one is found through the other; first wins;
announced. The self-test's per-bundle registry fails.
The section the Country Posters tab draws (a collapsible region head + its poster cards) is now usable on its
own, for any poster set, by parameters:
- library/components/poster/posterTypes.js: a TYPE REGISTRY. A type is an adapter (items for a scope, the
section's title, the print actions). The library registers 'country' (library data + the shared sheet path,
so a withheld whole-country poster stays withheld); plugins register their own types from their own code
(UPG 100 lists, regions, continents later). No plugin code in the library.
- 'country' scopes: a region key in any spelling. DX Life's /regions slug ('latin-america-and-caribbean'),
the API's value, the wall's slug and the English name all reduce to one canonical key.
- PosterSectionView.vue: one section, drawn by a PosterWall in a new SECTION-ONLY mode (no wall head; off by
default, so every existing wall renders as before), embedded so the page scrolls it.
- <dxm-poster-section type scope collapsible collapsed locale assets-base api-base-url is-dark>: the
attributes map onto the standard element's profile-config (posterSectionConfig.js, pure), so it keeps the
per-instance i18n and store. registerPosterSectionElement() from any bundle; Country Posters ships it first.
- country-posters/poster-section: a page showing two sections (Africa open, Oceania collapsed).
- poster.sectionNone (11 locales): an unknown type or an empty scope says so, never a blank.
check:poster-section (gates:pre) + self-test: the registry, DX Life's 8 scopes covering every country once,
withheld India, the attribute mapping, and PosterSection.vue injecting every name its template uses; 3 poisons.
The known collapse-while-scrolled landing is left exactly as it is.
