/* ==========================================================================
   FAQ / HELP CENTER — page-specific styles
   Rebuilt on the PianoMode design system: hero comes from design-system.css (.pm-doc-*),
   everything below consumes the semantic tokens (theme-aware, dark default +
   light parity) with no local --pm-* redefinition and no raw hex. All JS hooks
   (pm-faq-*) are preserved so faq.js keeps driving search / tags / accordion.
