/* GIB — the whole stylesheet.
 *
 * One file, published at /assets/site.css and linked by every page. Custom
 * properties carry the brand so a colour is changed in one place; the
 * palette is GIB's existing navy (#1F3066) and cyan (#07D6F6).
 *
 * No @import and no external stylesheet except Google Fonts: the platform
 * serves pages with `style-src 'self' 'unsafe-inline'
 * https://fonts.googleapis.com`, so anything else is blocked with no error
 * in the page — a blank-looking site and nothing in the console to explain
 * it. Fonts come from fonts.gstatic.com, which is the matching font-src. */
