Brotli has no magic signature: a truncated or non-brotli file is rejected by the decoder itself, and the message says exactly that. One stream per file: names and containers are gzip/zip territory, not brotli's.

Higher quality compresses smaller and runs slower (11 is glacial on large files). The wasm encoder runs in the archive worker; the page never blocks on it.
