 * Paste-URL allow list for upload fields (media / files / videos).

 * Configure via the NEXT_PUBLIC_PASTE_URL_ALLOW_LIST environment variable:
 *   - Comma-separated hostnames, e.g. "www.eversolo.com,am.luxsinaudio.com"
 *   - Bare hostnames default to https; you may also pass full "protocol://host" entries.
 *   - When the variable is unset or empty, the built-in defaults below are used.
 *
 * NOTE: NEXT_PUBLIC_ prefix is required so the client-side fetch interceptor
 * can also read this value at build time.
