/*
 * Front office stylesheet (F1.6) — one file, no framework, no third-party resource.
 *
 * Direction (FD9 is deferred: the brand sheet has not been provided): sober and light, derived from the colours of
 * the Flutter app (`#3FC96D` green, `#3F3E3F` text) so that the site and the app look related. The bright brand
 * green fails WCAG contrast against white, so it is only used for decoration and as a background under dark text;
 * links and buttons use a darker green (`--c-brand-strong`). Replacing the tokens below re-skins the whole site.
 *
 * Constraints kept on purpose: no inline style anywhere (the strict CSP of F2.1 will not allow `unsafe-inline`),
 * mobile first (min-width queries only), dark mode through `prefers-color-scheme`, and no JavaScript except the
 * optional privacy script of F1.7 (audience-measurement choice, click-to-play videos), never needed to read a page.
