Function fetchBlob

fetchBlob(
    servers: readonly string[],
    sha256Hex: string,
    fetchBytes: (url: string) => Promise<Uint8Array<ArrayBufferLike>>,
): Promise<Uint8Array<ArrayBufferLike>>
Fetch a blob by SHA-256 from a list of Blossom servers, returning the first server's bytes whose hash matches. The returned bytes are always re-verified against sha256Hex — servers (and gateways) are never trusted.
Parameters
- servers: readonly string[]
  Candidate Blossom server base URLs, tried in order
- sha256Hex: string
  The blob's lowercase-hex SHA-256
- fetchBytes: (url: string) => Promise<Uint8Array<ArrayBufferLike>>
  Fetches raw bytes for a URL (<server>/<sha256>)
Returns Promise<Uint8Array<ArrayBufferLike>>
The verified blob bytes

Throws
NappletResolutionError blob-unavailable if no server serves a hash-matching blob
