Data that remains active and readable should retain its normal foreground and background colors while another row is hovered. - -## Standards rationale - -Selectors Level 4 distinguishes `:focus`, which applies while an element has input focus, from `:focus-visible`, which additionally depends on user-agent heuristics about whether a focus indicator should be drawn. A skip link that is visually hidden until focused therefore uses `:focus` as the reveal boundary rather than relying only on the heuristic pseudo-class. - -WCAG 2.2 Success Criterion 1.4.3 requires minimum text contrast for ordinary visible text, subject to its stated exceptions. Applying opacity to an entire otherwise active row composites both text and background and can reduce the final rendered contrast. Because the actual ratio depends on all computed colors and the rendering environment, this change does not claim that the removed selector was universally nonconforming or that the resulting report is formally WCAG-conformant. It removes an avoidable contrast risk and retains exact visible content for all rows. - -## Verification contract - -`tests/test_report_focus_contrast.py` renders a realistic diagnostics report through the public `render_diagnostics_report` entry point and proves that: - -- the generated stylesheet includes a `.skip-link:focus` reveal rule alongside `.skip-link:focus-visible`; -- the focused link retains the strong repository-owned outline; -- the generated stylesheet contains no chart-peer opacity selector; and -- the generated stylesheet contains no table-peer opacity selector. - -The test validates deterministic generated markup. It is not a substitute for browser, assistive-technology, zoom, forced-colors, dark-mode, print, or user testing. - -## Compatibility and rollback - -The change affects presentation only. It does not alter report data, JSON parsing, numerical values, table semantics, export formats, model fitting, database objects, network behavior, or public Python signatures. Rollback consists of restoring the prior CSS selectors, but doing so would reintroduce the documented focus-reveal and contrast risks. - -## References - -World Wide Web Consortium.
