/* Notch — marketing site.
   Design philosophy borrowed from the "Message" template: near-black, cinematic,
   two-tone headings (bright lead + dimmed tail), dotted eyebrow labels, lots of
   negative space, and a fine film-grain texture over everything for depth.
   Standalone, no build step. Palette mirrors the app (src/app/globals.css). */
