   Palette "azure" baked from the Claude Design preview default.
   Interactivity is HTML/CSS-only (native <details>, :checked sibling
   selectors, :target lightbox, checkbox-hack nav). The only JavaScript on
   the site is the third-party Trustpilot widget bootstrap.
   The page markup keeps the design's inline styles, which reference
   var(--x, <azure fallback>); this file defines tokens, interactive state,
   semantic component styles and the responsive system.
