/* site.css — the shared visual shell for foundryos.ca CHASSIS-RENDERED pages.
 *
 * WHY THIS FILE EXISTS
 * The preserved hand-authored pages (index / about / assessment) each carry a large inline
 * <style> block that establishes the site's look: the dark theme tokens, the fonts, the fixed
 * top nav, and the footer. Pages the OAS chassis renders (articles + evidence + hubs) are NOT
 * hand-authored, so they cannot carry that inline block — without a shared stylesheet they render
 * as unstyled black-on-white content. This file consolidates the SHARED shell (tokens + reset +
 * body + nav + footer) copied VERBATIM from the live pages, plus the article/content typography
 * the chassis pages need (styling the emitted <main>, breadcrumb, CTA, and hub list). It is linked
 * into chassis pages via the OAS profile's `shell.stylesheets`. It is NOT loaded by the preserved
 * pages (they keep their own inline styles), so it can never double-apply or conflict with them.
 *
 * Reproduces the EXISTING design — the tokens, fonts, nav and footer are the live site's, unchanged.
