   ImageHalo — Landing page  ·  Aesthetic: "Foundry Noir"
   ────────────────────────────────────────────────────────────────────────────
   A premium dark atelier. Reuses the workspace's Linear/Vercel dark palette so
   the marketing page and the product feel like one object — but earns a memory
   anchor the workspace doesn't have:
     1. an editorial SERIF display headline (Fraunces / Song) against the
        utilitarian Inter UI, and
     2. a "living gallery wall" — real generated art scrolling in staggered
        vertical columns behind the hero.
   A single restrained warm-gold accent (drawn from the posters) threads through
   eyebrows and hairlines; everything else stays monochrome.

   Self-contained: does NOT import styles.css. The workspace stylesheet locks the
   body to 100vh / overflow:hidden, which would break a scrolling page — so the
   palette tokens are redeclared here and the body is free to scroll.
