+# Phase 16: Live Timing Polish
+
+## Goal
+
+Improve the React Live Timing route as an operations screen while preserving the
+existing official F1 SignalR bridge and TUI live behavior.
+
+## Completed Scope
+
+- Added pure helpers for position delta styling and race-control flag classes.
+- Improved the timing tower with podium position styling, colored position
+  deltas, best-lap/lap-count columns, and compact status badges.
+- Reworked the session banner so track status, lap count, clock, live/stale
+  state, and weather read as dense operational metadata.
+- Improved race-control feed treatment with color-coded flag badges, category
+  labels for non-flag messages, and bounded scrolling.
+- Reworked the live route layout into a two-column desktop view with timing
+  tower priority and race control alongside it.
+- Improved empty and disconnected states without requiring a real live F1
+  session.
+
+## Constraints
+
+- No backend live bridge or TUI live code was changed.
+- No persisted live storage was added.
+- Tests continue to use disabled-live/empty-state coverage because an active F1
+  session is not guaranteed.
+
+## Verification
+
+```bash
+npm --prefix frontend test -- --run
+npm --prefix frontend run build
+npm run test:e2e
+npm run test:e2e:prod
+npm run test:visual
+npm run test:visual:prod
+```
