/* =============================================================================
   NAILIVA STORE — BASE STYLESHEET ("Cream Editorial")
   Reset, design tokens, typography, buttons, badges, shared components.

   MOBILE-FIRST: base rules = mobile (no media query). Tablet (768px+) and
   desktop (1024px+) layered at the bottom via min-width media queries.

   DIRECTION: this palette + component set is reverse-engineered from the
   user's approved reference build (screenshots of the homepage, shop page
   and single-product page) — warm cream surfaces, near-black type/UI, a
   black announcement bar and header, serif display headings (Playfair
   Display) over an Inter body, sharp/minimal corner radius, no drop
   shadows, thin hairline borders. This intentionally REPLACES the
   "Onyx & Chrome" dark direction shipped in the previous iteration.
   Colors below were sampled directly from the reference screenshots
   (see /home/claude/refs in the build environment) rather than guessed.
