🎨 Palette: Improve table accessibility and typography

💡 What:

• Changed the first column in report tables from <td> to <th scope="row">.
• Updated CSS to style thead th and tbody th separately.
• Added font-variant-numeric: tabular-nums to table cells.

🎯 Why:

• Using th with scope="row" allows screen readers to correctly announce the identifying row context.
• tabular-nums ensures numerical data points align neatly on the vertical axis, improving overall readability in data tables.

♿ Accessibility:

• Significantly improved data table accessibility for screen reader users parsing the generated diagnostics reports.

Warning

Review limit reached

@seonghobae, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 28 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Comments suppressed due to low confidence (2)

python/fast_mlsirm/report.py:706

• tbody now uses <th scope="row"> for the first column, but the CSS rule that removes the bottom border on the last row only targets td. This leaves a visible bottom border under the last row’s first cell (the new tbody th), causing an inconsistent grid line.

tr:last-child td {
  border-bottom: 0;
}

.jules/palette.md:25

• The new palette note includes raw HTML (<th scope="row">) in Markdown, which GitHub may interpret as HTML and not display as intended. Wrap HTML/CSS snippets in backticks (or escape them) so the guidance renders consistently.

## 2026-07-22 - Accessibility for HTML reports
**Learning:** Generating semantic HTML tables for data reports is important for screen reader compatibility.
**Action:** Applied <th scope="row"> for first identifying column, font-variant-numeric: tabular-nums for styling, and separated CSS th matching between thead th and tbody th.
