/* Booboo — landing.
   NARRATIVE: hook → convince → prove (ruled with Jesse 2026-07-19).
   Act I is a dark, cinematic hero whose only job is to stop the scroll —
   legibility is deliberately not its concern. Everything after it turns LIGHT,
   because the thing that actually sells this is a working control surface and
   nobody should have to read an operating tool in a terminal. The transition
   from dark to light IS the argument: wonder, then clarity.

   Palette comes from tokens.css (generated from design/tokens.json, linked
   first). The light values here are the panel's own, so the landing and the
   board are literally the same object. */
