On a failed fetch the store now keeps the last real payload (stale > fake)
and flags `disconnected` instead of overwriting live data with bundled demo
data. Sample fallback is gated behind import.meta.env.DEV, so `vite build`
tree-shakes it out entirely (verified: no sample strings in dist).
- cold start / no data: centered reconnect spinner that keeps retrying
- data present + drop: stale data stays, header shows amber "reconnecting"
- polling retries faster (4s) while disconnected, recovers automatically
- sample.ts data moved into sampleOverview() so the module fully tree-shakes

Vue 3 + Vite 8 + TS + PrimeVue 4 (Nora/Industrial) + Pinia + vue-i18n SPA, served
by the SPRO gateway as a static page-module under /module/temper_overview and
embedded into Grafana via iframe.
- Ports the LOCKED design #4 "Shop-floor Schematic": one connected line
Pressen -> (cyan) -> Ofen -> (green) -> Fertig; carts under their origin press;
oven trays as dwell-progress bars; finished band; range picker scoping only the
Fertig figures. Flow/order colours match PressV (fleet recognisability).
- Python page-module wrapper: register(app) mounts committed dist/ + a no-auth
read API (GET /api/overview). Kernel DB seam in _db.py.
- Backend returns SAMPLE data; frontend falls back to bundled sample so `npm run
dev` renders with zero backend (TODO markers point at the real temper aggregates).
- Rich README bakes in the design, contract, wiring + Grafana embedding for
standalone development.
