Pull request overview

Improves keyboard focus visibility for the HTML diagnostics reportโ€™s skip-link target (<main id="main-content">) by adding a main:focus-visible style, addressing a WCAG Focus Visible gap when users activate โ€œSkip to main contentโ€.

Changes:

  • Add main:focus-visible outline styling (teal outline, offset, rounded corners) to make focus location visible during keyboard navigation.
  • Document the :focus { outline: none; } + :focus-visible pairing pattern in .jules/palette.md for future report UI work.

Reviewed changes

Copilot reviewed 2 out of 2 changed files in this pull request and generated 2 comments.

File Description
python/fast_mlsirm/report.py Adds main:focus-visible styling so the skip-link target shows a visible keyboard focus indicator.

## 2026-07-26 - Focus-Visible for Skip Links
**Learning:** While `outline: none` on `:focus` is necessary to prevent a focus ring when mouse-clicking programmatically focusable targets (like the main content area targeted by a skip-to-content link), it simultaneously breaks keyboard accessibility because the focus state is hidden for screen reader or keyboard-only users.
**Action:** Always add a corresponding `:focus-visible` block with a visible outline (e.g. `outline: 3px solid #0f766e;`) for any element that uses `:focus { outline: none; }` so keyboard navigators have a clear visual indicator of where they are on the page.
