 /**
- * check-mobile-gating.mjs — the SPA's device rules stay on the right shelves (DRV1650-MOBILE-GATING).
+ * check-mobile-gating.mjs — one phone flag per map, and every surface follows it (SPEC-MOBILE-FLAG,
+ * the per-plugin half of DRV1650-MOBILE-GATING).
  *
- *   DESKTOP_ONLY   production rows BLOCKED on a narrow screen (disabled + "desktop only" + a message)
- *   MOBILE_NOTICE  experimental rows that OPEN on a narrow screen, with a "not built for mobile" notice
- *
- * Headless: reads plugin-designs/doxa-maps-spa/doxa-maps-spa.vue and src/strings.js. It fails if:
- *   · a DESKTOP_ONLY id is not a curated (production) tab, or a MOBILE_NOTICE id is not an Experimental
- *     bundle (curated, excluded, or no plugin folder), or an id is in both sets;
- *   · the predicates stop reading their set and the narrow flag, or the pane notice stops rendering;
- *   · any locale lacks mobileNotBuilt / mobileNotice / dismiss / desktopNotice, or desktopNotice
- *     stops naming the map ({label}), which it must now that more than one map can be desktop-only.
- * `--self-test` proves every rule can fail on a planted bad case before trusting a pass.
+ * A map declares how it behaves on a narrow screen ONCE, in <profile>.meta.json:
+ *   "mobile": "desktop-only"     blocked on a phone (the Gallery disables its row; the leaf shows why)
+ *   "mobile": "larger-screens"   opens on a phone, under a dismissible notice
+ *   absent                       phone-ready
+ * generate-tree carries it into the manifest and the leaf page's BASE_CONFIG; the Research Gallery
+ * derives its rules from the manifest; ProfileLoader shows the leaf's notice. This fails if:
+ *   (a) a meta.json declares a value outside that vocabulary (a typo must not read as phone-ready);
+ *   (b) a flagged profile's leaf page does not carry the flag, or a leaf carries one its meta dropped;
+ *   (c) the Gallery hard-codes an id set again, stops deriving from the manifest, or stops failing
+ *       closed on a phone before the manifest lands (its baked first tab would mount there);
+ *   (d) dashboard-plus-grid stops being desktop-only — the migration must not soften that gate;
+ *   (e) a locale loses one of the notice sentences, or the desktop-only one stops naming the map;
+ *   (f) ProfileLoader stops mounting the notice, or stops staying quiet inside the Gallery.
+ * `--self-test` plants one bad case per rule and proves each can fail before a pass is trusted.

+                           Not an overlay, so it can never cover the map's own controls. The × emits

+  sentences, moved into the library catalogue so the Gallery and a standalone leaf say the same thing
