 - Browser: explicit Light persisted across Settings → Dashboard navigation and refresh; explicit Dark switched without navigation; System selected the browser's dark preference; a second tab inherited Dark and changing it to Light updated the first tab without reload.
 - Browser widths: 375, 768 and 1440; document width did not exceed the viewport after the tabs correction. Light 375/768 and Dark 1440 evidence is retained.
 - Browser console warnings/errors after the final interactive pass: none. Development HMR emitted transient module-update messages while source files were being edited; they were not present in the captured tab diagnostics and the clean production build passes.
+- Cross-application follow-up: every icon-only frontend control has an explicit accessible name; dark missing-job Alert contrast is measured from computed Chromium styles at WCAG AA 4.5:1 or better; public CV framing has no outer or inner overflow at 375px. Full frontend 54 suites/228 tests, build and Playwright 7/7 pass (V-170).
