Subject: [PATCH] The region card becomes a shared component the plugin
 consumes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Driver's ask, and his negotiating point with the DX-life author depends on it
being true: the components cloned from their /regions page must be REUSABLE,
PARAMETERIZED components in the shared library, not private to one plugin. He named
the failure mode himself — someone opens the regions plugin folder and finds the
components are not reusable after all. I checked before building, and for the UI he
named he was right: only the DATA and LOGIC had been promoted.

So library/components/regions/RegionSectionCard.vue takes title, summary, countries
and footerLabel, emits what was clicked, and knows nothing about where regions come
from. The plugin version fetched its own data and owned the layout, which is exactly
what made it unusable anywhere else.

THE DESIGN TRAVELS WITH IT. The card carries the region-card, countries-grid and
country-link CSS lifted unchanged — including the RTL chevron rules, where a
"forward" chevron must mirror in Arabic while a disclosure caret must not, and where
[dir="rtl"] .region-card__icon at 0-2-0 would otherwise beat the 0-1-0 --open
modifier. A consumer gets the look, not a lookalike. It needs dir on an ancestor for
that mirroring, which is documented in the file as a requirement.

★ THE CARD OWNS THE DISCLOSURE ROW, after the first cut got it wrong. I put the
"View country posters" toggle in the consumer's slot — and immediately had to copy
the footer-link styling and the rotating caret back into the plugin, re-creating the
duplication this extraction exists to remove. A disclosure inside a card is a card
feature; only the revealed CONTENT is the consumer's, so PosterWall stays in the
slot with its fourteen props and does not become every consumer's API.

★ THE CHEVRON IS INLINE, NOT A <use href="#id">. The plugin declared the symbol once
and every card referenced it. A shadow-root id is scoped to that root, so the same
card mounted elsewhere would reference a symbol that does not exist — and an
unresolved <use> renders NOTHING, silently. The plugin's own comment warns about
that class for external hrefs; a cross-root id fails the same way.

check:regions-uses-library is registered and asserts BOTH halves: the plugin imports
from @map/ and renders the component, AND no longer holds the markup or the CSS it
delegated. A reusability claim only a human can audit is one that rots; this one
fails the day someone re-inlines a copy. Two negative controls keep it honest — the
plugin still uses its own .rl-root classes, and the other tab is asserted NOT to use
the card yet, so the check describes what is extracted rather than what I hope for.

Two of my own mechanical edits produced valid JS and broken content on the way here,
both caught by checking rather than by the parser: a line-numbered splice that
dropped PosterWall's closing /> (fixed by locating boundaries by CONTENT), and a
line-filtered CSS deletion that left 9 orphaned declarations and braces at 12/21
(fixed by removing rules brace-aware, then re-validating the concatenated stylesheet
rather than trusting check:sfc-parse, which only proves the JS parses).

+/**
+ * RegionSectionCard.vue — one region as a card: a heading, a summary line, a grid of its countries,
+ * and a footer link. The DX-life /regions card, made reusable.
+ *
+ * WHY THIS IS IN library/. The Driver, verbatim: "let's say we want to reuse that on future plugins.
+ * We make it a reusable component, parameterized — you can set the region titles wherever you want
+ * them to be, fill in the countries to whatever you want them to be." The design is the point as much
+ * as the markup: the 156 lines of CSS below are lifted UNCHANGED from the regions plugin, so a caller
+ * gets the look, not a lookalike.
+ *
+ * ★ IT TAKES DATA, NOT AN API. The plugin version fetched its own regions and owned the layout, which
+ * is what made it unusable anywhere else. This takes `title`, `summary` and `countries` and emits what
+ * was clicked. Nothing here knows where regions come from.
+ *
+ * ★ THE CHEVRON IS INLINE ON PURPOSE, and this is the one thing a mover has to get right. The plugin
+ * declared <symbol id="chevron-up"> ONCE in its own template and every card referenced it with
+ * <use href="#chevron-up">. A shadow-root id is scoped to that root, so the same card mounted anywhere
+ * else would reference a symbol that does not exist — and an unresolved <use> renders NOTHING, with no
+ * error. The chevron would simply be missing. The plugin's own comment warns about exactly this class
+ * for external hrefs ("would 404 SILENTLY and the chevron would simply vanish"); a cross-root id
+ * reference fails the same way. So the path travels with the component.
+ *
+ * ★ RTL NEEDS AN ANCESTOR CARRYING dir, and that is a REQUIREMENT ON THE CONSUMER. The rules below
+ * include [dir="rtl"] .region-card__icon, ported because a chevron meaning "forward" must mirror in
+ * Arabic while a disclosure caret meaning "open/closed" must not — and the rtl --open rule is
+ * load-bearing, since [dir="rtl"] .region-card__icon is specificity 0-2-0 and would otherwise beat the
+ * 0-1-0 --open modifier and freeze the caret. The regions plugin satisfies this because .rl-root
+ * carries :dir itself. A new consumer must set dir on an ancestor inside its own shadow root, or the
+ * mirroring silently will not happen.
+ *
+ * ★ EXTRA CONTENT IS A SLOT, NOT A PROP. The regions plugin shows a country-poster wall under each
+ * card, configured with fourteen PosterWall props. Baking that in would have dragged one plugin's
+ * feature into every consumer's API. The `extra` slot keeps it where it belongs.

+  // because this element has no router, and `font:inherit` gave it 400 — MEASURED against
+  // their live /regions. Same class of miss as the dashboard back-link.
+  // The icon spacing is theirs too: .with-icon is inline-flex with align-items:baseline and NO
+  // gap (composition/_icon.scss:12), and the 1rem separation comes from
+  // `.with-icon .icon.right { margin-inline-start: 1rem }` — 10px at their 10px root. We had

+    // ★ text-align:START, not left. Theirs is a NuxtLink, an inline <a> that shrink-wraps to its

+  // same 102.7px of text, their label flush to the row's RIGHT edge (gap 0px, the RTL reading start)
+  // and ours flush LEFT -- every label stranded 144.2px on the wrong side. Invisible in English,
+  // which is exactly why it survived a 37-property card diff and an 11-property bullet diff.

+  // not a text glyph. Ported verbatim (fill:currentColor tracks the surrounding text colour,
+  // same as their `.icon{ fill:currentColor }` utility) and rotated 90deg to point right, same
+  // as their `rotate-90` class. getComputedStyle measured it at 33.38px square on the live page.
+  // ★ 1rem WAS THE ONE UNIT IN THIS PORT THAT INHERITS THE HOST PAGE'S ROOT, and it was wrong on

+  // element lives — which is the whole reason dxlife-tokens.js resolves their scale to px — and
+  // their root is 10px (html{font-size: var(--font-size-base)}, $font-size-base: 10px). Ours

+  // 10px, and on a host with the common html{font-size:62.5%} reset it would render 10px by
+  // accident. Pinned to the value their root produces, like every other token here.
+  // No diff caught it: the list diff's `link` spec reads colour, decoration, weight, display and

+ *
+ * THE DRIVER'S POINT, and the reason this check exists rather than a note: his negotiating position
+ * with the DX-life author is that cloning their /regions page into this bundler MADE ITS COMPONENTS
+ * REUSABLE for every future map plugin. He named the failure mode himself — "a load bearing assumption
+ * that could be proven wrong by going into the private plugin folder for the Regions plugin and seeing
+ * that actually the components are not reusable".
+ *
+ * So this asserts the thing that can be checked by opening the folder: the regions plugin must USE the
+ * shared components, and must NOT hold its own copy of what it uses. A claim about reusability that
+ * only a human can audit is a claim that rots; this one fails on the day someone re-inlines a copy.
