The header.cover_image pagemediaselect field had no accept filter, so the
Admin media picker listed every file in the trip page folder — including the
GPX files placed there by the GPX manager. On a typical trip page (photos live
on the journal entries, not the trip page) the picker offered *only* GPX, and
selecting one routed a non-image Medium into cropResize, rendering a broken
<img> on both the trips list and the trip banner.
- Blueprint: add `accept: ['.jpg','.jpeg','.png','.webp','.gif']` so the picker
only offers images (prevention at source).
- Macro: resolve cover_image against `media.images` instead of all media, so a
non-image or unresolvable selection falls through to the entry-photo
auto-pick (defence-in-depth; also hardens the R11 fallback).

Give trips an optional one-liner (header.tagline) and description (markdown
content), surface them where they help, and fix the soft cover image — all
editable from admin.
- U1: header.cover_image blueprint field → pagemediaselect media picker.
- U2: new macros/cover.html.twig — single source for cover resolution
(author-selected → first journal image → none; missing file falls back)
and retina rendering (1x/2x cropResize + srcset). Merged resolve+render
into one macro since Twig macros can't return a Medium object.
- U3: trip-list card renders the one-liner (when set) and the retina cover.
- U4: trip-page in-column header gains the one-liner, an expandable
description, and a thin banner strip — gated behind a trip_header_extras
partial flag (default off) so the shared home active-trip view is
unchanged (R12/KTD4).
- U5: styles for the card/header one-liner, collapsible description
(max-height preview, not line-clamp, so it holds across paragraphs) and
the banner, with a mobile banner-height reduction.
Covers R1–R15. Verified with new Playwright specs + full trip/home/maps
regression against an isolated worktree dev server.
