/**
|
|
* S15 — copies the MediaPipe Vision wasm runtime into `public/cards/mediapipe/`
|
|
* so the card cutout runs 100% same-origin (no CDN executing JS in the
|
|
* visitor's browser; the e2e suite never touches the network).
|
|
*
|
|
* The wasm is a gitignored build artifact: this script runs in `pnpm dev`
|
|
* (preflight), in `pnpm build` (npm `prebuild`) and in the Docker builder
|
|
* before `next build`, so both the dev server and the standalone image serve
|
|
* the files. Idempotent and cheap: a file already present with the same byte
|
|
* size is skipped.
