PostCard and PostModal competed for the same data and rendered redundant chrome (header twice, image grid twice, attachment list twice). The wider PostCard layout we shipped 2026-05-27 has enough real estate to be the canonical post surface, so collapse the two into one. Compact (default) state is unchanged: hero + 3-cell rail + truncated title + 3/5-line description + attachment count badge. Whole-card click expands in place. Expanded state shows: full title, mosaic of ALL post images via PostImageGrid (uncapped, lazy-loaded via getPostFull), full sanitized-HTML description with paragraph wrapping, attachments as downloadable pill links. Click the chevron in the header to collapse; mosaic image clicks open ImageViewer scoped to the post (modalStore's postImageIds path is preserved — only the comment changed). Per-card local state — no global modal store. Each PostCard owns its own expanded ref and lazy-loaded detail; collapsing a card discards neither (so re-expand is instant after the first fetch). Deleted: PostModal.vue, postModal.js store. Removed the App.vue mount.
