Two booth feed fixes:
- Plate not showing until refresh. Plate recognition is async/advisory
(snapshot.ts recognizePlate → a kind:"read" device_event keyed by the session
identity), so it lands AFTER the entry/exit event already shipped over the WS
without a plate; a refresh re-fetched via the bulk enrich path and showed it.
Added a `plate-recognized` bus event (device-events.ts) emitted when the read
is written; ws.ts forwards it; the client patchPlate(identity, plate)
(live-store) backfills the already-rendered feed row in place and invalidates
the Query-owned active-sessions list. No refresh.
- Plate search didn't filter. Both the live-feed (BoothScreen) and active-sessions
(ActiveSessions) search haystacks matched the wrong field — the displayed plate
is the ENRICHED top-level e.plate/s.plate (set by enrichEvent), not payload.plate
(the plate is unsigned, never in the signed payload). Switched the haystacks to
the displayed field.

The on-screen Hyrje/Dalje barrier lights were 2-state (green=free / red=busy)
off the camera lane-status only — they couldn't show the radar-only "detected,
not yet confirmed" state that makes the physical button lamp (relay 3) blink.
Now they mirror the lamp's 3-state rule per lane:
radar present + camera not busy → BLINK green↔red (~1 Hz)
camera busy → SOLID red
otherwise → SOLID green
End-to-end:
- LanePresence (lane-presence.ts): subscribes to deviceEvents.onInput, resolves
each presence edge to its lane via the new direction-agnostic presenceLaneOf()
(device-resolve.ts) — entry AND exit, unlike the entry-gated relayForPresence
the one-car-one-ticket gate uses — and emits a lane-presence {entry,exit} bus
event on change. Wired in server.ts (start + onClose).
- WS forwards it (hello snapshot + push) into live-store.radar.
- BarrierLight (BoothScreen.tsx) is now 3-state; blinks via the .lane-blink
keyframe (index.css), which holds solid-red under prefers-reduced-motion.
Same input + same rule as the lamp, so the screen and the post never disagree.
A new test (lane-presence.test.ts) caught a real bug: the first cut reused
relayForPresence, so the EXIT lane never resolved (it's entry-gated) and never
blinked — presenceLaneOf fixes it. Covers entry/exit independence, de-dupe
across several radars on one lane, and ignoring non-presence inputs.
Full workspace build/lint/test green (185 server tests). Updated the
button-light-indicator wiki page ("On-screen twin").

A Hikvision vehicle detection (eventType=VMD, targetType=vehicle) on a
camera bound to entry/exit now marks that lane "busy" and shows it as a
barrier light beside the scan input on the booth (green=free, red=busy).
Advisory only — it gates nothing (never blocks a ticket or opens a barrier).
- Parse eventState (active/inactive) from the Hik payload.
- LaneStatus tracker: a vehicle `active` event marks the camera's bound lane
busy + arms an auto-clear timer. This camera class sends no leave/`inactive`
signal, so "free" is timeout-driven (LANE_BUSY_TTL_MS, default 90s; the
camera re-fires `active` while a car sits there, refreshing the timer). A
"both"-direction camera marks both lanes.
- Push lane-status over the existing booth WS (+ in the hello snapshot);
live-store holds { entry, exit }; two BarrierLight icons render it.
- i18n booth.laneEntry/laneExit (sq + en).
Tests: lane-status.test.ts (7 — busy/free, TTL auto-clear, timer re-arm,
no re-emit while busy, both/exit direction, unknown device). server 120/120;
web + server build/lint green.

Generalise printer-only monitoring to every configured device. New
DeviceMonitor polls all enabled devices each tick (default 8s): printers
via rich readStatus(), relays/readers/cameras via the generic healthCheck()
reachability probe, flattened to one traffic-light (ready/degraded/offline)
+ detail, deduped (emit on change only), fail-toward-offline.
- device-status bus event + GET /api/devices/status snapshot.
- Pushed over the existing /api/ws (hello carries the initial set;
device-status frame per change).
- Web: live-store devices map, WS handler, DeviceFooter chip-per-device
(role label not vendor; click a degraded/offline chip for an issues panel).
Verified roleKind resolution + change-only emit on a fresh DB.
Note: the footer's UI surface (api type, router mount, i18n devices) rides
in the subsequent subscription commit due to shared-file overlap.

Add tailwindcss (Bloomberg-terminal theme in index.css), @tanstack/react-query +
react-router, zustand, and Radix primitives. Router with role-guarded routes;
QueryClient wrapping the existing apiFetch; a small Zustand live store fed by a
/api/ws client that invalidates Query caches. Booth screen: live occupancy gauge
+ streaming entry/exit/payment feed. Vite proxies the WS upgrade.
Note: BoothScreen references the pay/exit modal + active-sessions panel added in
following commits; final HEAD builds.
