/**
 * A cross-environment image {@link @nhtio/adk/batteries/media/contracts!MediaEngine}
 * backed by Jimp (pure JavaScript — no native bindings, no binaries).
 *
 * @module @nhtio/adk/batteries/media/engines/jimp
 *
 * @remarks
 * The local-by-default raster engine: runs anywhere TypeScript runs. Declares one mutate
 * capability over png/jpeg/bmp/gif/tiff with resize (cover/contain approximations), rotate,
 * flip, quality, and metadata stripping (Jimp re-encodes pixels, so EXIF never survives —
 * `strip_metadata` is inherently satisfied), plus a generation edge: `EMPTY_MIME` → a blank
 * 1024×1024 white canvas in any supported encoding (resize in the same statement —
 * `empty:png | image resize width=64`). For webp/avif output or native-speed processing,
 * compose a sharp-backed engine instead — the capability declaration is the seam.
 *
 * `jimp` is an optional peer dependency, lazily imported on first actual use (constructing
 * the engine — and therefore the pipeline — never loads it).
