// regression) to keep concerns isolated:
//   - visual: testDir tests/visual/ — pixel-perfect snapshots, brittle to copy
//   - a11y: testDir tests/a11y/ — semantic accessibility, blockers only
//
// Both share the same dev server (port 5173). `reuseExistingServer` lets
// `pnpm test:a11y` and `pnpm test:visual` run back-to-back without restart.
