/**
 * Shared foundation for every server-rendered /civic-action route.
 *
 * Design tokens, the global reset and the top-level layout primitives
 * (.app / .screen) that every route builds on. Loaded unconditionally by
 * templates/partials/app-head.php; per-route stylesheets (sign-in.css,
 * app.css) layer on top via $iod_styles.
 *
 * Palette: the site's light "brutalist" system — a cream surface, dark ink
 * text and an orange accent, with ink-alpha borders and the signature
 * `4px 4px 0` offset shadow. Headings use Space Grotesk, body Montserrat
 * (loaded via Google Fonts in the shared document head).
