/* ── Explore: the public directory ────────────────────────
   A minimal typographic index: serif names, one line each, hairlines and
   air. On wide screens a whisper-quiet rail lists every loaded AI by name;
   below ~1024px the rail disappears and the single column stands alone.
   Everything inherits the theme tokens, so light/dark just works. */
