 * Used by:
 *   - Explore › Posts chip → tile click
 *   - Home feed → "N Comments" link
 *   - any surface that calls window.devalayPostViewer.open(id)
 *
 * Markup is auto-injected by static/js/post-viewer.js so any page
 * that loads this CSS + JS gets the modal for free. The internal
 * `.post-viewer__*` namespace keeps the styles self-contained.
