system.pages.expires was 604800 (Grav default), so browsers cached feed HTML and entry media for a week with no revalidation — deleted entries lingered as ghost cards (images 404), and edited/new photos didn't appear until a hard refresh. Set expires: 0 → Cache-Control: no-cache, must-revalidate. With etag already on, an unchanged page returns a cheap 304; changed content shows immediately. Also fixes reorder staleness (photo-N.jpg is reused across reorders at the same URL). The server-side page cache (cache.enabled) is untouched. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
