/* ── Gallery: photo grid ──────────────────────────────────────────────────
   Reuses the Mac System 7 chrome tokens (tokens.css) plus .welcome-card/
   .card-header banner. Only the photo grid tiles are new here — the
   lightbox modal is global, see css/image-modal.css. No new breakpoints,
   same fixed 820px desktop layout.
