  Shared across every page: design tokens, base reset, the logo mark,
  the dropdown nav, the Sign Up CTA, the mobile hamburger menu, and the
  footer. Each page still defines its own `.site-header` positioning
  rule locally (the homepage needs position:fixed + pointer-events
  trickery to sit over the WebGL canvas; inner pages just want a plain
  sticky white bar) — that part is genuinely page-specific.
