Measurement snapshot on 14 October 2026, UI overview-ui-f56ddd996e42-74e1a8131ee8: 48/48 page-width-theme combinations passed document-overflow and >=44px visible button/input/select checks (six pages, four widths, two themes); 12/12 isolated theme/navigation checks passed; 33 existing overview/export/evidence tests passed in two invocations (32 + 1); 10 reviewed site captures were added by this session. Sources: [private evidence location omitted], theme-check-results.json, scoped pytest outputs and the approved public capture index. The exported snapshot also rendered and retained Light after reload in a local browser preview. Physical-device testing and direct file-URL launch remain unverified. The earlier 150-test project result is historical; no new simulation or sustained performance claim is made. See Project Overview Site documentation.
