/* ==========================================================================
   MESH Design Language (MDL) 1.0 — Component Library
   --------------------------------------------------------------------------
   Canonical, token-driven component classes for the MESH web surfaces. These
   are ADDITIVE and namespaced (.mesh-*), so adopting them is opt-in and cannot
   regress any existing page. Existing component classes (.button-primary,
   .empty-state, .status-pill, .badge, .account-panel, .site-card, .notice)
   keep working unchanged; new/standardized UI should use the classes below,
   and existing UI can migrate incrementally in MDL 1.1.

   Depends on mesh-tokens.css (loaded first). Every value references a token —
   no hardcoded colors here.
