+### Shared trip-feed-col partial
+
+The home page's active-trip view and the trip page render the **same feed-col chrome** (date-range header, filter bar, stats/cycling panels, feed loop) via one shared Twig partial. This is separate from the feed-map partial above — it is the column **beside** the map, not the map.
+
+- **Partial:** `user/themes/intotheeast/templates/partials/trip-feed-col.html.twig`
+- **Used by:** `trip.html.twig` and the active branch of `home.html.twig` (both via `{% include ... with {...} only %}`)
+- **Sibling:** `partials/home-predeparture.html.twig` — the home-only "Coming soon" landing state. `home.html.twig` picks it with `{% if all_items|length == 0 %}` → `home-predeparture` `{% else %}` → `trip-feed-col`. Keep `trip-feed-col` single-purpose — do NOT fold the pre-departure branch back into it.
+
+**Parameters (`trip-feed-col`):**
+
+| Parameter | Type | Trip passes | Home-active passes |
+|---|---|---|---|
+| `trip_page` | Page | `page` | `trip` |
+| `all_items` | array | sorted by date, flag 4 (oldest→newest) | sorted by date, flag 3 (newest→oldest) |
+| `journal_entries` | array | dailies children | dailies children |
+| `journal_count` / `story_count` | int | counts | counts |
+| `has_gpx` | bool | `has_gpx` | `home_gpx_urls\|length > 0` |
+| `gpx_urls` | array | `gpx_urls` | `home_gpx_urls` |
+| `gps_points` | array | `gps_points` | `gps_points` |
+| `show_sort` | bool | `true` | `false` (home keeps its own feed order, no sort button) |
+
+`home-predeparture` takes only `trip_page`.
+
+**Stats/cycling JS glue:** the partial emits an inline `DOMContentLoaded` script calling `window.initTripStats({ gpxUrls, gpsPoints, hasGpx })` — one shared function in `js/src/main.js` (rebuild with `make build-assets`; never hand-edit `js/main.js`). It no-ops when `#stat-distance` is absent, populates exact distance + cycling stats from GPX, and falls back to a `~`-prefixed haversine estimate (or `—` for `<2` points) when there is no GPX. It depends on `window.MapUtils` from `map.js` (loaded in the `bottom` asset group on both pages).

 ### GPX file management
 
 GPX files are stored as page media on the trip page (`user/pages/01.trips/<slug>/`). They are picked up automatically by `map.html.twig` via `trip_page.media.all`.
