+`src/ui/statusBadge.js` constructs/updates ordinary badges without listeners,
+status inference or live-region policy. It consumes translated text and controlled
+visibility; appearance variants share CSS rather than mapping machine states to
+universal severity. CCTV owns frame/source and calibration rules and their data
+attributes, while Weather owns coverage labels. The keyed rail-card owner keeps
+node identity, header focus, disclosure and teardown. The shared adapter never
+creates another state store or announces all card updates. A Vue view can replace
+this adapter and retain these presentation inputs and styles.

+## Ordinary status badges
+
+CCTV source/frame labels, calibration provenance and Weather coverage labels use
+`ui/statusBadge.js` and the `gev-status-badge` CSS surface. The listener-free
+adapter accepts already-translated `label` and `hidden` values; pill, box and plain
+appearances describe shape/density only. Static CCTV markup uses the same classes
+as generated rail-card badges. Repeated identical updates do not rewrite text or
+replace nodes. Empty coverage remains hidden.
+
+Feature owners retain the status rules, machine-state attributes, translations
+and announcement policy. CCTV frame acquisition (`idle/loading/error/ready`)
+remains separate from provider status: retained pixels do not imply a healthy
+feed. Calibration still distinguishes manually saved, catalog-curated and raw
+prior poses; unsaved edits override the label until save/reset. Coverage labels
+remain geographic scope, not health claims. Existing colors and the source
+badge's polite live region are preserved; coverage and calibration do not gain
+live regions. Interactive layer toggles, progress indicators and world overlays
+retain their specialized ownership. Vue can reuse the view contract and CSS while
+replacing DOM construction. Browser acceptance:
