/* ==========================================================================
   COMPONENTS — the company-wide component library (the shared root DS).
   Written ONCE against canon token names (var(--...)). A client's design-lock
   token VALUES skin every component — same names/structure, different brand.
   Client themes include this file + their tokens.css; Claude Design derives
   from the preview/ cards. BEM · mobile-first · tokens only (no raw hex/px).

   Atomic Design tiers: ATOMS (button, tag, folio, section-title) → MOLECULES
   (card, field). ORGANISMS (header, hero, sections, footer) live in each
   client theme and graduate up here only once they repeat across clients.
