Optimize optional JPEG decode and encode paths with DC-only IDCT, separable AAN transforms, reciprocal quantization, and retained SIMD color conversion. Harden WASM stack, panic, and buffer boundaries. Add pinned PR-only Imazen corpus validation with per-file baseline comparison and retained benchmark evidence.
Add explicit Node and browser loaders, bounded VP8 and VP8L kernels, SIMD VP8L transforms, corpus validation, browser coverage, benchmarks, generated package metrics, and documentation.
Use lazy in-memory transform storage by default and make temporary files an explicit, probed opt-in with graceful fallback and cleanup retry. Harden JPEG WASM exactness, add forced JPEG and PNG scalar/SIMD Imazen lanes alongside WebP, and refresh canonical benchmark reports, charts, metrics, and documentation.
Remove dependencies on ignored benchmark corpus files from the WebP WASM suite. Generate the odd RGBA and lossy VP8 inputs in memory and use the checked-in lossless fixture so clean CI checkouts exercise scalar, SIMD, and fallback paths.
Decode XML entities without double unescaping, read conformance files through a stable file handle, and bound benchmark and browser-test delays. Remove two no-op timestamp replacements and add regression coverage for nested XML entities.

Reject viewer benchmark delays above the bounded one-minute ceiling before creating a timer so the resource-exhaustion guard is explicit to both runtime callers and CodeQL.
