/**
 * poster-wall.vue — the UPG-100 POSTER WALL (pane 2 of the my-upg-100-list family).
 *
 * @description A wall of printable poster cards, one per 100-list entry, each with a "Show on map"
 *   action that hands off to the map profile in the same bundle.
 *
 * ★ MIGRATED ONTO THE SHARED WALL 2026-09-24. This file was 890 lines carrying its own copy of
 * markup, CSS, the export modal and three print paths; the rendering now comes from
 * @map/components/poster/PosterWall.vue, which country-posters (94 lines) and key-cities (75)
 * already consume. This profile supplies ONLY what cannot be shared: its data, its taxonomy and
 * its records provider.
 *
 * WHAT COULD NOT BE SHARED, and why each is here rather than in the component:
 *   REGION_OF / regionFor  — the 100-list's own continental taxonomy, keyed by list id because a
 *                            selector can be a wagf_block, a country_codes array or an explicit
 *                            pg_slugs list and none of those implies a continent.
 *   fetchListRecords       — knows the people-groups API, the selector evaluator AND the pg_slugs
 *                            special case. Key Cities and Country Posters have entirely different
 *                            data shapes, which is exactly why the shared wall takes a PROVIDER.
 *
 * THREE CAPABILITIES HAD TO BE ADDED TO THE SHARED WALL FIRST, over two ticks, because migrating
 * without them would have REGRESSED this wall rather than consolidated it:
 *   cardStocks             — the reader picks the prayer-card size at print time.
 *   posterAction="print"   — open the print dialog instead of saving a file.
 *   hidePrayerListWhenSoon — no "coming soon" placeholder on a wall whose list DOES print.
 * The last two are a Driver ruling, not a preference (2026-09-23): "three print buttons, each
 * opening an in-browser print dialog, no silent file download as the default action. A raw
 * 'Download' button and a 'Prayer List: coming soon' placeholder were exactly the two buttons he
 * objected to."
 *
 * CROSS-PANE COMMS — unchanged and still the decoupling that matters: this wall NEVER imports the
 * map. The shared component dispatches the window CustomEvent named below, scoped by instanceId,
 * so several embeds on one page never cross-talk. The shell listens and drives the map pane.
 *
 * ASSETS. previews/<id>.webp (~65KB, 378 generated) SHIP and are what the wall paints. Full
 * posters/<id>.webp do NOT ship by default (~42MB); export and print fall back to fetching
 * posters/<id>.html and rasterising it in the browser. See
 * IDEA-POSTER-EXPORT-404-ON-DROPPED-FOLDER-TRADEOFF.

  // CENTRAL ASIA is its own section. Brief: "the 55 UPG Pakistan map is wrongly
  // added to Middle East, it is Central Asia." It had been folded into the Middle
  // East as "the same sweep continuing east", but Pakistan, Afghanistan,

// below reads it directly. Passing regionFor straight in built and loaded cleanly and
// then threw `c.startsWith is not a function` at first render: the whole wall was blank,
// 0 cards, with nothing wrong at the source layer.
// ★ THE ENGLISH VALUES ABOVE ARE GROUPING KEYS; THIS TRANSLATES AT RENDER (studio's split).
// REGION_OF keeps its English values as stable identity — changing them would re-key the
// grouping — and the heading a reader sees is resolved here, per locale, through REGION_KEY

// One flat list of the zones the map paints — for WHICHEVER list is showing.
//
// ★ THROUGH zonesForList, not a static clusters.json import (pattern work, 2026-09-27). This wall already
// filtered its RECORDS by list (applyPeopleGroupList, below), so before this it showed another list's
// people groups arranged under UPG-100's zone names — half list-aware, which is the worst of the two
// states because it looks right. Now the zones follow the list too.
// Safe inside a computed: profileConfig is injected at :54 and this evaluates lazily, after setup —
// a module-level call would hit the temporal dead zone (it does in upg-100-list.vue, which is why that
// file resolves per call as well).
// ⚠ AND THE OLD COMMENT SAID "the same 27", which was already stale: the legend has 28 leaves, because
// buildLegendNodes collapses the two deaf_lists into one unified row. This spread still yields 27 because
// it reads the three geographic buckets and the deaf row is synthesised — so the number is right for what

// This wall kept its own fetch (the field list, the reader's language, list membership, normalisation
// and the pg_slugs special case). All of it is the print standard's records provider now, which every
// map shares, so a fix to any of it reaches every wall. What is THIS profile's is only the selector
// language: pg_slugs is understood by the provider; every other UPG-100 selector goes through the same
// evaluator the map uses, so the map, the list print and the card deck cannot disagree about membership.

// drawn in the browser for the poster print and the packet's page 1 — data/zone-sheet-print.js, the one
// helper every UPG-100 surface prints a zone through.
const zoneSheet = makeZoneSheet({ allRecords: () => recordsFor.all(), assetsBase: () => assetsBase.value, profileConfig })

// The wall's own copy. v-html in the shared component, so the <strong> lands as markup —
// the emphasis is the point: praying for them BY NAME is the whole brief.
//
// ★ THROUGH t(), NOT A LITERAL. rega measured ?lang=ar and found this intro, the heading and
// the tag rendering in English while the wall's buttons beside them were translated — the
// copy a reader reads FIRST was the untranslated part. The <strong> travels inside the
// translated string so each language can emphasise its own words, which is not something a
// wrapper around an English sentence could do.
// Guarded like every other useI18n() here: it throws on a host without vue-i18n. useOptionalT stores
// that guard once (host i18n -> catalogue -> the key) instead of a hand-rolled copy.
// No namespace: callers pass FULL keys here, exactly as the raw useI18n().t they used to get.
//
// ★ ONE BEHAVIOUR GAIN FROM WAVE 3c (regions-plugin, 4c05e589): the old path was the bare
// useI18n().t, so on a host WITH i18n a missing key rendered the raw dotted key. It now falls through.
//
// ★ AND THE humanizeKey FALLBACK IS GONE — the one deliberate departure from 4c05e589, which kept it.
// It rendered a key's last segment title-cased, so a bare host showed "Upg100 Wall Intro" where a
// whole SENTENCE exists: wrong even in English, and untranslatable because it comes from the
// identifier rather than a catalogue. It was kept on the theory that these keys were not fully
// catalogued — I told regions-plugin exactly that, and it was FALSE: this file's three keys are
// present in all ELEVEN locales, 0 gaps (enumerated 2026-09-27; the only three, all string literals).
// ⚠ IT GUARDS A BARE HOST, NOT A MISSING KEY. Those are different failures and I had them confused.
// Product call taken by dx-shepherd (UPGHK, 2026-09-27) under the Driver's standing goal that the
// production maps be localized.
const t = useOptionalT('')

// ★ THE MARKUP IS COMPOSED HERE, so the CATALOGUE holds plain text (dx-shepherd UPGHTML, 2026-09-27).
// vue-i18n warns "[intlify] Detected HTML in '…'" twice per tab pass, and it is right to: a translated
// string carrying <strong> is the only one in this tree that does — I measured every en catalogue area
// and upg100WallIntro is 1 of 1, so this was not a convention, it was my outlier.
//
// ⚠ WHY THE OBVIOUS FIXES DO NOT APPLY HERE. The shepherd's suggestion — markup in the template, or
// <i18n-t> interpolation — assumes this profile renders the sentence. It does not: `intro` is a STRING
// PROP on the library PosterWall, rendered there with v-html (PosterWall.vue:955), and that component
// has no slots at all. So the markup has to arrive inside the string, and the only question is who
// builds the string. Building it HERE keeps the catalogue clean without a library change.
//
// ★ AND IT IS STRICTLY SAFER THAN WHAT IT REPLACES, which is the part worth keeping. v-html on a whole
// catalogue string TRUSTS THE CATALOGUE: any tag a translator (or a bad merge) puts in any of the 11
// locale files renders as markup. Composing here escapes each part and emits exactly one tag I control,
// so the trusted surface shrinks from "every translation of this key" to "this line".
//
// THREE PARTS, NOT A WRAPPER AROUND ONE, because the emphasis is not in the same place in every
// language. Measured across all 11 locales: each has exactly one <strong> and no other tags, and de, hi
// and zh carry real text AFTER the emphasised run (" beten.", " प्रार्थना करते हुए।", "為他們禱告。")
// where the others end on a full stop. A head+emphasis wrapper would have silently dropped those tails.

  // all eleven locales, so the branch is now DEAD CODE — and dead code that names a key keeps that key
  // alive: studio cannot delete upg100WallIntro while this line reads it (their L13U measurement).
