/* PatYap marketing site — shared styles.
   Brand tokens are the app's own (source: docs/dark-mode-tokens.md, the Claude
   Design "PatYap" project). Warm paper world: cream canvas, orange accent,
   Newsreader serif headlines / Hanken Grotesk body / Zen Kaku for JP glyphs.
   Light mode only — the warm cream IS the brand (same call as the store set). */
