On a failed fetch the store keeps the last real payload (stale > fake) and
flags `disconnected` instead of falling back to bundled demo carts — an
operator must never book a reject against a fabricated entry. Sample data and
sample reason codes are gated behind import.meta.env.DEV, so `vite build`
tree-shakes them out entirely (verified: no sample strings in dist).
- cold start / no data: centered reconnect spinner that keeps retrying
- data present + drop: stale carts stay, header shows amber "reconnecting"
- reasons no longer seed sample codes in production
- polling retries faster (5s) while disconnected, recovers automatically
