#
#   wai/wai-app/e2e/run.sh [--only create,built,refused,own,agent]
#
# 1. wai-relay and wai-room (crates joule-moq-relay and joule-moq-room; native, release), and `wai` with its features
#    `quickstart` (the receipts its writes leave, and `wai verify`) and `app` (wai/wai-rs, in a target directory of its
#    own: two workspaces build wai-rs differently);
# 2. the WebAssembly packages, through wasm-bindgen's web target, each with its own --out-name,
#    into the runtime directory: joule-moq-web (room/moq/pkg/wai_room_moq), wai-live-web
#    (room/live/pkg/wai_room_live) and wai-app with its feature `web` (create/pkg/wai_app);
# 3. the runtime laid out as the site serves it (web/runtime.mjs): create/ and room/; and the
#    room client `wai dev` serves at /room/ (wai/quickstart/build-web.sh);
# 4. the page modules' unit tests (node --test web/web.test.mjs);
# 5. the browser-automation package from e2e/package-lock.json (`npm ci --ignore-scripts`),
#    outside the tree unless PLAYWRIGHT_HOST names one installed;
# 6. e2e/create.e2e.mjs in the browser BROWSER_BIN names (the host's installed one), else the
#    package's own.
#
# Environment: CARGO_TARGET_DIR (one target directory for every workspace), BROWSER_BIN,
# PLAYWRIGHT_HOST, CREATE_E2E_OUT (where the runtime and the results go), CARGO_LOCKED
# (default --locked). Nothing listens beyond loopback.
