Fast-follow (c) from the offline plan: a Playwright mock e2e that auto-covers the whole offline / local-game flow (previously only contour-verified + unit-covered).

What the spec does (e2e/offline.spec.ts, both Chromium + WebKit):

  1. Forces the installed-PWA display mode (a matchMedia stub) so the Settings offline toggle is offered.
  2. Enters offline through the real toggle — its readiness check fetches every enabled variant dawg.
  3. Asserts the blue header chrome, that online games (vs Ann) are hidden, and the Stats tab is disabled.
  4. Creates a device-local English vs_ai game with a pinned bag seed (deterministic rack NEWYMAO), taps out the opening WAY across the centre, and watches the local robot reply with a real move.
  5. Reloads and asserts the game replays from IndexedDB intact.

Enabling infra — all e2e-only, nothing enters the production build:

  • mock/client.ts fetchDict now serves the per-variant dawgs from the preview build /e2edict/ (was: threw).
  • scripts/e2e-dict.mjs copies the real dawgs into dist-e2e/ from E2E_DICT_DIR; playwright.config runs it between build and preview. The ui CI job fetches the scrabble-dictionary release the same way the Go jobs do; locally it defaults to the sibling scrabble-solver/dawg. Dawgs are never committed (dist-e2e/ is gitignored) and are tree-shaken / absent from the prod build.
  • localgame/id.ts setForcedSeed + gateway.ts window.__mock.setLocalSeed: a mock-only seed seam (tree-shaken from prod).
  • docs/TESTING.md documents it.

Verified local: check 0 / unit 482 / e2e 198 (Chromium+WebKit) / app entry 113.8/114 KB.

A Playwright spec drives the whole offline flow in the mock build: force the
installed-PWA display mode, enter offline via the Settings toggle (its readiness check
fetches the dawgs), assert the blue chrome + online-games-hidden + Stats-disabled, then
create and play a device-local English vs_ai game with a pinned bag seed (deterministic
rack NEWYMAO) -- play the opening WAY across the centre, watch the robot reply with a
real move, and reload to confirm the IndexedDB replay.

Enabling infra (all e2e-only; nothing enters the production build):
- mock/client.ts fetchDict serves the per-variant dawgs from the preview build's
  /e2edict/ (was: threw 'unsupported in mock').
- scripts/e2e-dict.mjs copies the real dawgs into dist-e2e from E2E_DICT_DIR (the ui CI
  job fetches the scrabble-dictionary release like the Go jobs; local default: the
  sibling scrabble-solver/dawg); playwright.config runs it between build and preview.
- localgame/id.ts setForcedSeed + gateway.ts window.__mock.setLocalSeed: a mock-only
  seam to pin a local game's bag seed (tree-shaken from prod).
- ci.yaml ui job: fetch the dawgs + pass E2E_DICT_DIR to the e2e step.
- docs/TESTING.md: the offline e2e + the mock-dawg wiring.

Verified: check 0 / unit 482 / e2e 198 (both engines) / app entry 113.8/114.
