/* ============================================================
   WebBLE Shared Components — single source of truth for every
   reusable primitive (buttons, cards, sections, code blocks,
   forms, prose, callouts, FAQ, layout helpers).
   Load AFTER design-tokens.css, BEFORE page-specific CSS.

   This file serves as the component library for secondary /
   marketing pages (pricing, mcp, changelog, for-hardware-companies).
   It is NOT loaded on index.html, docs.html, demo.html, or
   dashboard.html. Any selectors here that overlap with home.css
   are intentional fallbacks/overrides for those secondary pages.

   NOTE: Selector duplication with site.css is intentional.
   site.css is loaded on the home page; components.css provides
   the same base styles for secondary pages that don't load
   site.css. Changes to shared selectors must be applied in
   both files.
