A poster type registered by another plugin's bundle (upg100-list, by
my-upg-100-list.js) could only say No posters on a Poster Sections preset
page, which loads poster-sections.js alone. src/typeScripts.js names such
types and their bundles; the page adds the bundle as a second <script>, once
per page, when the type is not registered yet (the registry is one per page),
and re-resolves the type when its registration is announced, so all regions
lists the type's regions as they arrive. Copy embed carries the same second
script. The Configure picker offers these types before their script runs,
named from the catalogue (posterSections.typeUpg100List, 11 locales).
check:poster-sections: every preset's type is the library's own or listed in
src/typeScripts.js with its bundle in the built tree; its self-test proves a
preset whose type no script registers fails.
A preset page loads only poster-sections.js, so a preset of a poster type
registered by another plugin's script (upg100-list) could only say No
posters. The generator now gives no presets to a type whose file is not on
the tree, and check:poster-sections fails on any such preset: 9 presets
remain (7 regions, all regions, configure).
The tree generator writes a page per preset but never deletes one, so the
dropped presets' pages (the 10 upg100 ones and countries-other) are removed,
and a new arm holds the built preset pages to exactly the presets.
gen:poster-sections-presets writes poster-sections.instances.json from each
type's scopes() (all regions, then one preset per region titled by the type's
own section title in the site's English, then configure), the same list
check:poster-sections holds the file to. Today it reproduces the 20 presets
exactly, in the data's region order; when the data's regions change, running
it is the whole fix.
The presets file now has to hold, per poster type, exactly an all-regions
preset plus one per region the type's adapter returns from scopes(). A region
the data drops (a stale "other") or gains then fails the check, instead of
lingering as a preset. 'country' is measured always; 'upg100-list' once its
type file is on the tree. Self-test: a preset for a region the type does not
have must fail.
A new bundle, plugin-designs/poster-sections, with one profile, Poster Sections.
A panel of choices (poster type from the registry at runtime, region or All
regions, language, posters per row, start collapsed) drives the library's
<dxm-poster-section> elements shown live below it, and Copy embed gives the
bundle script plus the exact tags for those choices, with absolute URLs so they
work on another site. The bundle also registers <dxm-poster-section>, so a site
that loads only poster-sections.js can place the tags.
Library: the element takes a columns attribute (posters per row, 1-5), passed
to the wall's existing columns prop; absent keeps today's default, so existing
importers are unchanged. New catalogue area posterSections in all 11 locales.
check:poster-sections (in gates:pre) reads every panel choice back through the
element's own attribute reader; its self-test proves a builder that drops
columns, drops collapsed, or repeats a region under All regions fails.
