      The stored theme choice, applied before first paint (see
      src/ui/theme.ts). It cannot wait for the module script: a dark choice
      would flash light on every load. Light needs nothing: it is stamped on
      <html> above. "system" is resolved here, contrast first, and followed
      while the page is open. Keep the key, the choices and the resolution in
      step with theme.ts: its test runs this script to check.
