/* NotchViber for Claude Code - notchviber.com
   Concept: MIDNIGHT DESK. A MacBook Pro in a dark room; the site is the scene.
   The real notch demo lives inside a CSS-built laptop. Film grain, aurora
   wallpaper, desk reflection, cursor tilt, scroll zoom, variable-weight type.
   Radius: interactive 10px, nested media 10px, screen 3.2%/22px.
   Dark locked: it is a room at night. */
