/*
  noibi web — landing, privacy, support.
  Colours mirror src/design-system/tokens (palette.ts / colors.ts, light mode:
  the app is fixed to light while the brand system settles, so is the site).
  Type follows D8: Hiragino / Noto Sans JP, never italic, generous line-height.
  Page transitions, reveals and scroll effects are CSS-only progressive
  enhancements. The only script is the わが家 demo on the landing
  (room-demo.js + the app's room engine), same-origin, so the CSP in _headers
  allows script-src 'self' and nothing else. Without it the page still reads
  completely: the demo falls back to a still of the room.
