/*
  AEVOR site. One stylesheet. System fonts, no image or font fetched from anywhere, no web address in it.

  Layers, in order: tokens, base, header, controls, hero (logo build and plan drawing), the iPad frame and its media slots, then one
  block per section, then scroll-driven motion, then the plain pages (privacy, support, 404), then settings that change how it must look.

  Motion rules for this file:
    - Everything is finished and readable with no animation. Animation only adds a way in ("both"/"backwards" fill), never hides content.
    - All of it sits behind prefers-reduced-motion: no-preference. With reduce, nothing moves, nothing plays, no parallax.
    - Scroll-driven animations (animation-timeline) are used where the browser has them. Where it does not, assets/site.js sets
      html.nosda and the same effects run from one IntersectionObserver or one scroll handler.
    - No inline styles anywhere (the Content Security Policy forbids them): every value is here.

  Scripts/verify_site.sh reads the token block below (between the "tokens:" markers) and fails if a text/background pair falls under
  WCAG AA (4.5:1 for text, 3:1 for the focus ring). Keep one token per line, "--name: #rrggbb;", so it can.
