/**
 * =================================================================================
 * PHP BUILT-IN SERVER ROUTER  +  DASHBOARD ENTRY POINT (index.php)
 * =================================================================================
 * Dual-purpose file:
 *   • When run as a PHP cli-server router script, intercepts every request and
 *     dispatches it to the appropriate .php handler (clean-URL support for dev).
 *   • When loaded directly (as /index or / on the dashboard), bootstraps the
 *     layout engine and renders the Videos Registry tab.
 *
 * ROUTER SECURITY NOTE
 * ─────────────────────
 * The router ONLY serves PHP-handled routes. Requests for static assets (JS, CSS,
 * images, etc.) return false so the built-in server handles them natively.
 * This prevents the router from accidentally falling through to layout.php
 * (which calls requireLogin()) for any request that isn't a known PHP route.
 * =================================================================================
