Covers routes/activities that enter the journal without BRouter waytags
(imports, uploads, pre-existing rows):
- overpass-ways.server.ts: server-side Overpass client (way[highway] + geom in
a bbox, configurable OVERPASS_URLS, timeout + oversized-bbox guard).
- surface-match.server.ts: pure nearest-way map-matcher → per-segment
surface/highway (unmatched → unknown). Unit-tested.
- surface-backfill pg-boss job: load geom → skip if breakdown exists → Overpass
→ match → computeSurfaceBreakdown → store → emit `surface_breakdown` SSE to
the owner. Idempotent, retry-safe, best-effort; registered in server.ts.
- Enqueued from createActivity (imports/uploads) + owner-on-open in the route &
activity detail loaders (non-Planner routes, old rows), deduped via singletonKey.
- useSurfaceBackfillUpdates: detail pages subscribe to /api/events and
revalidate() when their row's backfill lands (live bars, no reload).
- Privacy manifest updated (DE + EN) for the Overpass bbox lookup.
Tests: matchSurfaces unit; surface-backfill job (mocked Overpass/db/events:
store + emit, skip-if-present, skip-if-no-ways). Verified the real
Overpass→match→breakdown pipeline against a live Berlin bbox (509 ways →
plausible asphalt/paving_stones/footway mix). typecheck + lint + unit
(journal 333) green.
Note: the worker runs via server.ts (prod/staging), not `react-router dev`, so
the live job + SSE exercise on a deployed instance.

Synchronous path + rendering for the surface/waytype breakdown:
- map-core `computeSurfaceBreakdown(coords, surfaces, highways)` → distance-
weighted metres per surface + waytype category (unit-tested);
- `SurfaceBreakdownSchema` in @trails-cool/api;
- nullable `surfaceBreakdown` jsonb on routes + activities;
- Planner `SaveToJournalButton` computes it from the BRouter waytags already in
routeData and sends it; `api.save-to-journal` forwards it; the journal route
callback validates + persists (journal is the authoritative validator);
- `SurfaceBreakdown` component (stacked bars per dimension, map-core palettes,
legend category · % · km largest-first, unknown → "other", hidden when empty)
on route + activity detail; journal gains a @trails-cool/map-core dep;
- i18n journal.surface.* (en + de).
Phase 2 (async Overpass backfill + SSE for imports/uploads, and the e2e that
seeds a breakdown) follows in a separate PR.
Tests: computeSurfaceBreakdown unit (map-core 36); SurfaceBreakdown component
(jsdom, journal 326). typecheck + lint green; verified in the browser.

Builds on the merged A-only proposal. Broadens the capability:
- breakdown now on routes AND activities;
- Path 1 (sync) unchanged: BRouter waytags → breakdown at Planner save;
- Path 2 (async): a `surface-backfill` pg-boss job map-matches geometry to OSM
via Overpass for imports/uploads/older rows, stores the breakdown, and pushes
a `surface_breakdown` SSE event so an open detail page fills in live;
- privacy note: backfill sends geometry to Overpass → route via the proxy /
self-hostable Overpass; documented in the manifest.

Surface + waytype proportion bars on route detail, from the BRouter waytags the
Planner already computes (and currently discards on save). Design records the
data-source decision: persist a compact distance-weighted breakdown for
Planner-created routes (accurate, no external call); Overpass map-matching for
imports/uploads is parked as a future option.
