/* ============================================================
   AI INTERVIEW PORTAL — DESIGN SYSTEM
   ------------------------------------------------------------
   Palette & type are deliberately chosen for a proctoring /
   AI-assessment product: a deep "signal-room" navy background,
   a violet primary accent (the AI), a cyan secondary accent
   (the live feed / recording state), and amber reserved only
   for scoring & warnings so it stays meaningful.

   Signature element: the "Readiness Ring" — concentric pulsing
   rings behind the camera/mic glyph on the login card, echoing
   a live waveform / face-detection reticle. Reused later as the
   recording indicator during the actual interview.
