Description
The MediaKeySystemMediaCapability dictionary has no MDN page. It's used in the audioCapabilities and videoCapabilities arrays passed to Navigator.requestMediaKeySystemAccess(), so it's central to any EME usage.
It has three members:
contentType— MIME type of the media resourceencryptionScheme— the encryption scheme ("cenc","cbcs","cbcs-1-9", ornullfor any)robustness— required CDM robustness level
Spec: https://www.w3.org/TR/encrypted-media/#mediakeysystemmediacapability-dictionary

Research direction
Start with the MediaKeySystemMediaCapability definition in the linked Encrypted Media Extensions specification and its use in Navigator.requestMediaKeySystemAccess() audioCapabilities and videoCapabilities. Create the missing MDN page documenting contentType, encryptionScheme, and robustness, including the listed allowed encryption values; done means the dictionary and its members are clearly covered.
