/**
 * Solvyr App Center — "Control Tower" design system
 *
 * Premium light platform-console skin: Solvyr blue accent on near-white
 * surfaces, 1px hairlines, 8px radius, Sora display + Inter body.
 * Loaded app-locally AFTER shared tokens.css/solvyr.css (zero blast radius
 * to sibling apps). Restyles the shared chrome via CSS only — depends on
 * the shared partials' stable hooks:
 *   header.sticky-top .navbar.bg-dark   (shared_assets/partials/header.php)
 *   footer.bg-dark                      (shared_assets/partials/footer.php)
 *   .toast-container.position-fixed     (shared_assets/partials/footer.php)
 * If shared markup ever changes, only the CHROME sections here need updating.
