Visual baselines were generated as chromium-darwin.png on macOS; CI on
Linux looked for chromium-linux.png and every test failed with
"snapshot doesn't exist". Override snapshotPathTemplate to omit the
platform suffix so darwin and linux share the same baseline. Pixel
diffs from font hinting are an accepted trade-off — visual regression
gives signal for big visual breaks, not 1-pixel differences.
Existing 26 baselines renamed from *-chromium-darwin.png to
*-chromium.png to match.
Adds 13 new visual regression baselines:
- Public: about (desktop + mobile), members (desktop + mobile)
- Authenticated desktop: member-account, member-activity, connections,
admin-dashboard, members-detail
- Authenticated mobile: member-dashboard, member-profile,
member-account, connections
Switches to a single serial test.describe with a beforeAll that logs in
once and saves the auth cookie via storageState. This avoids repeated
/api/dev/test-login calls that exhausted the dev server's MongoDB
connections under parallel execution.
Masks added: .tl-time, .stat-val, .item-date, .mc-avatar, .cc-avatar,
.profile-avatar, .filter-count — covering activity timestamps, stat
values, member join dates, avatars, and member counts.
