/*
 * Age Evolution — shared site stylesheet
 *
 * Foundation only. No page-specific overrides here.
 *
 * Palette tokens preserve the current production identity. They are exposed
 * under --ae-* names so future pages built from /src/pages/ can adopt this
 * stylesheet without a visual shift.
 *
 * Status taxonomy:
 *   .badge-live              Strong teal — capability is in production
 *   .badge-live-capability   Teal at reduced strength — capability is real,
 *                             external proof still limited
 *   .badge-pilot             Warm amber — active but not final
 *   .badge-roadmap           Outline only — future direction
