Add accessibility defect metrics to dashboard (#5679)
* Add accessibility defect metrics to dashboard (#4405) Add a new Accessibility section to the metrics dashboard that tracks a11y issues by defect severity level (0-3) over time as a multi-series line chart. Includes data collection in collect-issue-metrics.js, D3 visualization with quarter boundary markers, hover highlighting, interactive legend, and a table view with Jekyll-rendered data. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * Resolve Copilot PR review comments on a11y defect metrics - Compute 5-year chart cutoff dynamically from latest data period - Fix y-axis rendering when all values are zero - Remove unused periodIndex variable - Add missing IDs to imposter data-freshness elements - Update test assertions to match current dashboard structure (9 sections) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * Pad a11y monthly data with zero-count months and add keyboard accessibility to chart - Pad processA11yDefectMonthlyData to emit every month between min/max, ensuring table and chart show the same continuous timeline - Add focus/blur handlers to chart data points and legend items so tooltips and series highlighting work for keyboard and touch users - Add ARIA roles and labels to interactive chart elements Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * Update src/_about/metrics/index.html Co-authored-by: Jeana Clark <117098918+jeana-adhoc@users.noreply.github.com> * Update src/_about/metrics/index.html Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Fix va-table stacked mode at mobile widths by toggling sortable dynamically va-table disables stacked (responsive) mode when sortable is set. Remove sortable from static HTML and add JS that toggles it based on viewport width using the same 29.99em breakpoint va-table uses for stacked CSS. Tables now stack on mobile and gain sort headers on wider screens. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * Fix chart a11y issues and regenerate padded metrics data - Add zero-width guard for chart rendering in hidden tab panels - Remove excessive tab stops from chart data points (200+ circles) - Change legend items from role="button" to role="img" with descriptive labels - Regenerate issue-metrics.json with fully padded monthly data (no gaps) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * Remove redundant client-side month padding from a11y chart The collection script already pads monthly data to continuous periods, so the client-side padding loop was duplicating that work. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * Make h1 count assertion resilient to layout changes Use toBeGreaterThanOrEqual(1) instead of toBe(2) so the test does not break if the Jekyll layout adds or removes headings.
