+/**
+ * copy-pwa-icons.mjs — rename the @vite-pwa/assets-generator outputs to the
+ * stable filenames the hand-maintained manifest references (WR-08).
+ *
+ * The generator emits preset-named files (pwa-192x192.png, …). The manifest in
+ * vite.config.ts references stable names (/icon-192.png, …) so a generator
+ * version bump that renames its outputs surfaces here as a clear, named error
+ * rather than an opaque shell `cp: cannot stat`. This replaces a Unix-only `cp`
+ * chain so Windows contributors and minimal CI containers can run `pwa:icons`.
+ *
+ * Keep COPIES in sync with the manifest `icons` array in vite.config.ts.
