/* /brand/ (MODEL-299). Loaded after /landing-assets/landing.css, which brings
   the self-hosted faces, the axis line and the buttons.

   Theme tokens are the decide page's, so the two pages look like one site:
   light from `.decide-app`, dark from `.decide-app[data-theme="dark"]`, both in
   web/src/decide/decide.css. Brand colours (--navy, --yellow, --green, --blue)
   are landing.css's :root tokens, the same hexes as brand/2a/README.md.
   Dark unless the visitor picks light, as on /decide/ (MODEL-213). */
