 ### Trip entity architecture
 
 The site is structured around Trip entities. Key facts:
 - Active trip is set in `user/config/site.yaml` → `active_trip: japan-korea-2026`
 - Trip pages live at `user/pages/01.trips/<slug>/`
 - Each trip has: `01.dailies/`, `02.map/`, `03.stats/`, `04.stories/`
-- Nav in `base.html.twig` derives all links from `config.site.active_trip`
+- Site nav in `base.html.twig` has Home + Past Trips only — does not link to trip sub-sections
 - Post form parent (`post-form.md` → `pageconfig.parent`) **must be kept in sync** with `active_trip`
+- The trip page (`trip.html.twig`) uses a **client-side filter bar** (All content / Journal / Stories) — do NOT add nav links back to `/dailies`, `/stats`, `/stories` on the trip page
+- Stats are shown inline on the trip page via a toggle; the standalone `/stats` sub-page still exists as a URL but is not linked from the trip page
 - GPX route files live as media on the trip page itself, served via leaflet-gpx CDN
 - Manage GPX files (view/upload/delete) at `/gpx-manager` — requires admin login; filenames are auto-slugified on upload
