   HOMEPAGE — Page-specific styles
   Foundation (body, type, nav, brand, buttons, footer, theme
   toggle, variant pill) lives in aivz-shared.css.
   This file contains ONLY:
   - Hero section (.hero with scanline + grid backdrop)
   - Right-rail diagnostic card (.demo-card, .gauge, .layers, .firehose)
   - Section-specific layouts (.three-beat, .companion, .platforms,
     .personas, .category, .authority, .final-cta overrides)
   - Light-mode overrides for all of the above
