Make browse school accordions accessible to screen-readers

[piercebrookins]

What I did

• Replaced clickable school header <div> elements with semantic buttons inside level-three headings.
• Added and synchronized aria-expanded, aria-controls, and panel visibility.
• Preserved the existing layout and styling.
• Added accessibility regression tests.

Testing

• Verified Tab, Enter, and Space keyboard behavior.
• Confirmed screen readers expose each accordion as an expanded or collapsed button.
• Ran Ruff, djLint, and git diff --check.

Summary by CodeRabbit

• Accessibility

  • Improved school section controls with native buttons and clearer expanded/collapsed state information for assistive technologies.
  • Added accessible relationships between school headers and their department lists.

• User Experience

  • School sections now open and close more reliably while keeping visual and accessibility states synchronized.
  • Improved school header layout with full-width, left-aligned content and vertically stacked text.

📝 Walkthrough

Walkthrough

The browse page now renders school accordions with accessible buttons, ARIA relationships, synchronized panel visibility, updated header styling, and tests for the markup and toggle script.

Changes

School accordion accessibility

Layer / File(s)	Summary
Semantic accordion markup and styling tcf_website/templates/site/catalog/components/_school_section.html, tcf_website/static/css/site/pages/browse.css, tcf_website/tests/test_browse.py	School headers now use heading-contained buttons with ARIA attributes. Department panels support conditional hiding. Header text uses the updated layout styles. Tests validate the rendered structure.
Accordion toggle state synchronization tcf_website/templates/site/catalog/browse.html, tcf_website/tests/test_browse.py	The toggle script updates aria-expanded, is-open, and grid.hidden from the current accordion state. Tests validate these updates.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to acc56

The PR improves keyboard and screen-reader access for browse-page school accordions without changing application behavior beyond the UI interaction. It is otherwise low risk, but the stylesheet must be cleaned up because it currently violates the repository’s configured lint rule.
