Capabilities

• CORS proxy: Intercepts fetch and XHR requests matching stream manifests (.m3u8, .mpd, .ism) or media files (.mp4, .webm, .mkv, etc.) and routes them through GM_xmlhttpRequest, which ignores same-origin policy.
• Media element patching: Intercepts src / currentSrc assignment on <video>, <audio>, and <source> elements, fetches the content via the same proxy, and sets a blob URL so the browser plays it natively.
• Header stripping: Removes content-security-policy and related headers from proxied responses so embedded content loads without CSP blocking.
