   Vibe-coder map. Everything you'd ever want to tweak lives in the
   TOKENS block right below. Change a value there, the whole site
   follows. Nothing magic, nothing buried.

   SECTIONS (search these banners to jump):
     "TOKENS"          → all colors / sizes / timing in one place
     "BASE"            → reset + page defaults
     "HERO"            → the page: logo, tagline, "Coming Soon"
     "SHADER"          → the canvas background behind the hero
     "RESPONSIVE"      → phone / tablet adjustments
