Merge branch 'main' into feat/post-location-override

Brings the branch up to user/main, which was ahead on both content and
theme fixes. Notably e17a5dc ("block submit on unfinished photo uploads;
un-squeeze EXIF portraits in lightbox") — the branch point predated it, and
its absence is why UG1, UG2 and LD1 failed here: the upload gate and the
oriented-derivative slide dims those specs assert simply were not on this
branch. Also picks up denmark-2026 `published: true`, so the local testing
flip is no longer needed.

js/src/post-form.js auto-merged cleanly, keeping both main's upload gate and
this branch's location-override panel + lazy maplibre CSS link. The only
conflict was js/post/post-form.js, a generated bundle — resolved by
rebuilding via make build-assets rather than hand-merging minified output.
