/* Vox Book: page styles.
   Load order: globals.css (design system), voxbook-theme.css (Vox Book colours),
   then this file. Every value is a design-system token. Component rules follow the
   RedStone site, which uses the same system.

   Dark bands (header, hero, sign-up, footer) set data-theme="dark" in the HTML, so
   the system's dark tokens apply inside them and the light tokens everywhere else. */
