/*
 * Documentation site theme.
 *
 * The palette is lifted from the product's own landing page (frontend/app/
 * globals.css) so the docs and the platform read as one thing: navy for
 * structure, gold for the single action that matters on a screen, and a blue
 * that is only ever used for links and accents.
 *
 * Kept separate from the application stylesheet on purpose — this site ships
 * from a different build and must not be able to affect the product's CSS.
