/**
 * Whistle assets: the pinned manifest, where the files live, and the
 * first-use download.
 *
 * Three files make up the engine — the Cactus "needle" runtime (an Emscripten
 * build: `needle.js` + `needle.wasm`) and the Whistle speech model
 * (`whistle.cact`). They are fetched from pinned Hugging Face revisions on
 * first use, verified against a SHA-256, and written atomically (temp file +
 * rename), so an interrupted download never leaves a file that looks complete.
 *
 * Both upstream repositories are Apache-2.0.
