/* Sight4 marketing site, "sticker sheet" retro direction (founder pick, 2026-10-21).
   Palette: the sunglasses symbol (orange, mustard, sea-glass, ink) on warm paper, plus teal and rust
   from the retro deck for text. Bright decoration colors never carry text; text pairs meet WCAG 2.2 AA.
   Status colors (ok, block, info) stay the product's own and always come with an icon and a word.
   Nothing is loaded from a third party.
   Display face: Fraunces (SIL OFL 1.1, site/fonts/Fraunces-OFL.txt), self-hosted from google/fonts,
   subset to Latin and converted to woff2. Variable axes: opsz, wght, SOFT, WONK. */
