/* ==========================================================================
   The media system's exhibition and lightbox (D66, design.md at the repository root §05; shared since D71)
   The editorial wall of prints and the native <dialog> that shows a photograph whole. Loaded on the home page
   (07 · The Living Travel Exhibition) and on every tour and package page with a Gallery tab, after styles.css,
   living-cape-system.css and buttons.css. Markup: src/partials/media.mjs; behaviour: assets/js/media.js. The
   wall carries .lc-scope outside the home page's .living-cape, and the dialog always does, so the tokens of
   living-cape-system.css apply wherever they hang. Nothing here matches the hero, the header or .leaf-btn.
   ========================================================================== */

/* 1. The wall: an editorial mosaic on an explicit grid. Each print's span and ratio come from its record
   (photoExhibition, media.mjs): two columns on phones and tablets, feature tiles across both; from 64em a
   12-column grid, where one print per row states its ratio and the others stretch to that row (their
   photograph is absolutely placed, so it never sets a height). */
