/* ═══════════════════════════════════════════════════════════════════════════
   ARCHIVES — BASIC  (v7 · cinematic editorial index)
   --------------------------------------------------------------------------
   Goals of this rewrite:
     · Eliminate the grid-image horizontal overflow bug on phones / tablets
       (every grid track is minmax(0,1fr); every grid item has min-width:0).
     · A genuinely modern sticky sidebar index that *moves with the scroll*
       and reads like a film-strip table of contents.
     · A cinematic editorial atmosphere — subtle ambient glow, gold accents,
       restrained motion — that matches the cinematic mode in feel.
