/* ADC sign-in card. Copy verbatim to public/signin.css.
 *
 * Kept out of brand.css so the brand tokens stay one reviewed file, and out of
 * app.css so an author editing their own page rules cannot change what an
 * unauthenticated visitor sees. Colours come from brand.css only -- no literals
 * here beyond the two neutrals the palette already allows.
