Phase 14: Visual Regression and Responsive QA

Goal

Add Playwright screenshot coverage for the MVP Web UI routes across desktop, tablet, and mobile viewports before broader product expansion.

Scope

Routes:

/race-hub?session_key=9472
/data-library
/live (empty state with BOXBOX_DISABLE_LIVE=1)

Viewports (deterministic Chromium):

Project	Size
desktop	1280×800
tablet	768×1024
mobile	390×844

Commands

# Dev proxy (Vite + seeded Go API) — same stack as test:e2e
npm run test:visual
npm run test:visual:update

# Production serving (Go + frontend/dist) — canonical for committed snapshots
npm run test:visual:prod
npm run test:visual:prod:update

Snapshots live under tests/visual/__snapshots__/{desktop,tablet,mobile}/.

Constraints

Reuses scripts/seed-e2e-db and BOXBOX_DISABLE_LIVE=1; no live F1 session or OpenF1 network calls.
Screenshots are taken only after route-specific ready conditions (classification loaded, data library detail visible, live empty state).
Animations disabled; full-page captures; no loading-state screenshots.

Out of Scope

Live timing tower screenshots (requires an active session and live SignalR).
Cross-browser matrix beyond Chromium.
Pixel-perfect parity between Vite dev and production builds (use prod update when refreshing committed baselines).
