/* stillpub landing styles.
   No build step, no external origins: everything here is hand written and
   served from the same host as the pages. Colors come from the signal-orange
   brand ramp documented in app/public/brand/README.md.

   Theming: the light palette is the base. Dark is applied twice, once for
   people whose system asks for it (unless they picked light) and once for the
   explicit data-theme="dark" choice written by theme.js. */
