 * that fetches the original, resizes with sharp, and caches the result.
 *
 * For media.eliseai.com URLs, rewrites to /_img/media/{id}.{ext}?w=...
 * For /assets/ URLs, rewrites to /_img/assets/...?w=...
 * For other URLs (external, data:, etc.), returns as-is.
 *
 * When no resize options are provided, returns the original URL unchanged.
