/* ============================================================
   Shared cream-theme stylesheet for SIUU MAGIC static SEO landing
   pages: /couple, /pet, /product, /selfie, /pricing, /en.
   Hand-synced from /studio/studio-landing.css (2026-08-03) — that
   file was built+approved first (cream/paper day-theme, per user
   feedback "Nền kem paper chứ?" on 2026-07-30) and is left untouched
   on purpose so the already-shipped /studio page carries zero risk
   from this rollout. This file = same base + the extra component
   classes the other 6 pages need that /studio doesn't use:
   .use-card, .muted, .fine-print, .price-grid, .price-card
   (+.featured), .price, .list, .note-band.
   Standalone static file (outside the Vite/React build), so tokens
   are a hand-copied snapshot of the app's light-theme + Dusk aura
   values (see docs/redesign-design-system.md). If either the app's
   tokens or studio-landing.css change, re-sync both files by hand.
