/**
 * Parse a video URL into an embed descriptor. Supports YouTube and Vimeo.
 * Returns null for URLs we don't recognize (the caller should treat those as
 * raw `<video src>` files). Used by VideoElement renderers to switch between
 * `<video>` and `<iframe>` rendering.
 *
 * Important: embed URLs cannot be captured by the server-side export pipeline
 * (cross-origin iframe content isn't accessible to Puppeteer's `__tick` virtual
 * clock and YouTube's player ignores any external time signal). We surface
 * this as a warning in the properties panel.
