/* =====================================================================
   audioMCP.ai — WAITLIST MODAL
   DESIGN PROTOTYPE ONLY — REQUIRES PRODUCTION REIMPLEMENTATION
   ---------------------------------------------------------------------
   This stylesheet is layered on top of the compiled GitHub Pages build.
   It reuses the site's existing design tokens (CSS custom properties
   defined on :root by the production bundle) so the modal reads as
   native audioMCP.ai UI. Nothing here should ship as-is; the development
   team must recreate this in the real React/Vite + Tailwind source.
   See WAITLIST-DESIGN-HANDOFF.md.
