   LP-only styles. Loaded AFTER styles.css. Every class is namespaced `lp-`

   Design: "Say it with us" - Duolingo fun x Apple polish x Notion order.
   Palette mirrors the actual app (constants/Colors.ts, "Laifu Pop System v2"):
   warm cream base, CORAL primary CTA, gold + mint accents, yellow/coral chat,
   ink text. Expo Red/Blue are app-mark-only and NOT used as page accents.
