Complete block reference (6 blocks)
Store project-scoped named bytes and expose replayable raw body snapshots without converting data to base64 or text.
Set globalThis.BINARY_DATA_MVP = true before loading the unsandboxed extension.
Create binary data from UTF-8 text, test and delete names, and inspect MIME type, byte length, and SHA-256.
The JavaScript API accepts ArrayBuffer and Uint8Array. The Named Data provider exposes project-scoped raw snapshots for HTTP responses.
