fix: route leaderboards rank by moving time not elapsed — top-10 route times and route completions list now use COALESCE(moving_time_s, duration_s) so mid-activity pauses don't inflate times (consistent with moving-time avg pace)

After the build finishes, run `docker compose pull && docker compose up -d` there. This matches the repo rule: fix files in `~/milevault`, push to git — never patch the running containers in `~/milevault_docker`.

 **PocketID OIDC**: Optional passkey auth. Config is read from the admin user's DB record first, falling back to env vars. The OAuth callback redirects to `/?token=<jwt>` and `useAuth.js` extracts the token from the URL at module load time.
 
+**Personal records source filter**: Personal records are computed only from watch-recorded FIT activities; phone/Strava GPX/TCX imports are excluded because their GPS can "teleport" and produce bogus fast splits. Keep this filter in mind when touching `compute_personal_records` / `recompute_personal_records_all`.
+
 ### Frontend (`frontend/src/`)
 
 - `App.jsx` — React Router v6, `RequireAuth` wrapper, all routes defined here
 - `hooks/useAuth.js` — Zustand store for auth state, reads JWT from `localStorage`, handles PocketID token-in-URL flow
 - `hooks/useSync.js` — Zustand store polling Garmin sync status; maps backend status strings to progress percentages
+- `hooks/useUnits.js` — Zustand store for the global km/mi display preference (`useUnit()` subscribes to the active unit). Distances are stored canonically; the unit only affects display, converted on the fly by the `format.js` helpers. Persisted to `localStorage`. Surfaced in the nav via `components/ui/UnitToggle.jsx`
+- `hooks/useMediaQuery.js` — responsive breakpoint hook (md=768px split); the dashboard widget grid must be conditionally mounted, not just CSS-hidden, on mobile
+- `hooks/useMapSettings.js` — Zustand store for the global map tile preference: provider + style + per-provider API keys. **Persisted server-side on the user record** (`users.map_settings` JSON), with localStorage only as a first-paint cache. `useHydrateMapSettings()` (called in `Layout`) loads it from `GET /profile/`; mutations debounce-save to `PUT /profile/map-settings`. The provider/style catalogue lives in `utils/mapTiles.js` (`MAP_PROVIDERS`, `resolveTile`); every Leaflet map (`ActivityMap`, `RouteTileMap`) resolves its base layer via `useResolvedTile()`. The default Thunderforest key is **not baked into the bundle** — the backend supplies it via `settings.thunderforest_default_key` in the profile response, and `useResolvedTile` falls back to it when the user hasn't set their own. Configured in Profile › Map & Tiles. `ActivityMap` takes a `satellite` boolean to override with imagery (MapTiler satellite if keyed, else free Esri)
 - `utils/api.js` — Axios instance with JWT interceptor and 401→redirect handler

+- TanStack Query (`@tanstack/react-query`) handles all server-state fetching and caching; Zustand is used only for auth, sync, and unit-preference state
 - `utils/format.js` — shared formatting helpers: `formatDuration`, `formatPace`, `formatDistance`, `formatCadence`, `hrZoneColor`, `sportIcon`, `sportColor`, etc.
-- `utils/track.js` — projects a lat/lng onto a GPS track (interpolated along-line snapping, used for map hover and segment selection); `utils/bodyBattery.js` — shared Body Battery colour/state helpers used by both the Health page and Dashboard mini chart

-- `pages/` — one `*Page.jsx` file per route: `Dashboard` (drag-to-edit widget grid), `Activities`, `ActivityDetail`, `Routes`, `Records`, `Health`, `Upload`, `Profile`, `Users`, `Login`
+- `pages/` — one `*Page.jsx` file per route: `Dashboard` (drag-to-edit widget grid), `Activities` (type/year/date-range/distance filters + week totals), `ActivityDetail`, `Routes`, `Records`, `Health`, `Summary` (all-time and per-year/per-sport totals + distance-per-year chart), `Upload`, `Profile`, `Users`, `Login`
 - `components/activity/` — `ActivityMap` (Leaflet), `MetricTimeline` (Recharts), `HRZoneBar`, `LapTable`, `SegmentsPanel` (per-activity segment efforts), `RouteLeaderboard` (top-10 by pace for a named route)
-- `components/ui/` — `Layout` (nav shell), `StatCard`, `RouteMiniMap` (small Leaflet map used in route/segment cards)
+- `components/health/` — `SleepHypnogram` (renders the `sleep_stages` hypnogram), `BodyBatteryChart` (Body Battery trend chart)
+- `components/ui/` — `Layout` (nav shell), `StatCard`, `RouteMiniMap` (small Leaflet map used in route/segment cards), `RouteTileMap` (route-card map tile), `SportIcon`, `UnitToggle` (km/mi switch), `HrvBadge`
 
 The Vite dev server proxies `/api` to `http://backend:8000` (for use inside the Docker Compose network). The production build bakes `VITE_API_URL` at build time.
 
+### Request routing & browser caching
+
+There are **three** nginx configs and they serve different roles — don't confuse them:
+
+- `nginx/nginx.conf` is the **dev** reverse proxy mounted by `docker-compose.yml`: one nginx that proxies `/api/`→`backend:8000` and `/`→`frontend:80`.
+- `nginx.conf` (repo root) is the near-identical reverse proxy mounted by `docker-compose.deploy.yml`, for generic two-file deployments (see README). Keep the two in sync when touching proxy behaviour.
+- `frontend/nginx-spa.conf` runs *inside the `frontend` image* and only serves the built SPA (the `milevault_frontend` container). It has no `/api` proxy.
+
+**The actual production stack here does not use either reverse proxy.** `~/milevault_docker/docker-compose.yml` is a hand-customised compose (not the repo's deploy file): it drops the nginx service and routes via Traefik container labels — `Host(...) && PathPrefix(/api)` → backend, `Host(...)` → frontend SPA. The empty `~/milevault_docker/nginx.conf` (a directory Docker auto-created for a since-removed mount) is an unused leftover. So if a request reaches the SPA nginx with an `/api` path it falls through to `index.html` (returns HTML, not JSON) — a sign Traefik routing, not nginx, is the thing to debug.
+
+**Caching policy (set deliberately; a wrong change here strands users on stale builds):**
+- Hashed assets (`*.js`/`*.css`) → `Cache-Control: public, immutable` (1y) in `nginx-spa.conf`.
+- `index.html` → `no-cache` (must revalidate) in `nginx-spa.conf`, so new deploys are picked up without a manual cache clear.
+- All `/api/*` responses → `no-store`, added by an HTTP middleware in `backend/app/main.py`, so browsers can't cache authenticated state (e.g. a stale "Garmin not connected").
+
+### Deploy verification
+
+After `./deploy.sh`, the Gitea Actions build (`validate` → `build-backend`/`build-worker`/`build-frontend`) must finish before `docker compose pull && up -d` picks up new `:latest` images. Poll completion via the API rather than guessing:
+```bash
+curl -s https://gitea.jarrett.eu/api/v1/repos/owain/MileVault/actions/tasks
+```
+The runner builds images on-host, so local image digests won't match the registry — verify a deploy landed by `docker exec`-ing into the running container and grepping the changed source, not by comparing digests.
+
+Always deploy the changes requested, do not prompt the user whether to deploy.

+Strava API sync helpers.
+
+OAuth: exchange_code() / refresh_tokens() talk to Strava's token endpoint.
+get_valid_access_token() transparently refreshes an expired access token and
+persists the rotated refresh token.
+
+sync_strava_activities() lists the athlete's activities, fetches per-activity
+streams, builds a fit_parser-shaped dict and hands it to persist_activity()
+(shared with the file-upload path) so Strava activities get identical dedup,
+PR, route and segment handling.
+
+Tokens are Fernet-encrypted with the same SECRET_KEY scheme as Garmin creds.
