resolves #1392

🧭 Context

  • The heading was a link to the section anchor so clicking the obvious target jumped you somewhere you could already see
  • The thing that actually collapsed the section was the small arrow beside it

📚 Description

  • The arrow and the label are now one button inside the heading (as suggested by @knowler)
  • The anchor link is now a separate icon button after the heading
  • Added uppercase label as the reset was removing text transform.
  • Made the copy icon always visible
  • Dropped the toggles aria label since the visible text already says what it does so I removed the unused collapse_with_name and expand_with_name
  • Added tests for the toggle, aria controls, button placement and copy button accessible name

Open question

The title used to be a LinkBase for navigation but I changed it to a real copy button like Code/Header.vue. Deep links still work but section jumping doesnt

  • should I keep it as a normal link instead?? Happy to change it just lmk:)

📝 Summary

Summary by CodeRabbit

  • New Features
    • Collapsible sections now provide clearer accessible controls, including expanded/collapsed state information.
    • Added an option to copy a direct link to a section, with confirmation feedback after copying.
  • Localisation
    • Updated translation resources and schemas for section-link actions and newly supported interface areas.
  • Accessibility
    • Improved coverage and validation for collapsible section controls and section-link buttons.

Walkthrough

CollapsibleSection now uses its heading as the expand/collapse control and provides a separate copy-link button. Translation schemas and locale placeholders were updated. Accessibility tests cover the new structure and behaviour.

Changes

Collapsible section interaction

Layer / File(s) Summary
Section control and copy-link behaviour
app/components/CollapsibleSection.vue
The title is now inside the toggle button. The component uses aria-expanded and aria-controls. A separate button copies the section URL and shows a copied state.
Translation contract and English strings
i18n/schema.json, i18n/locales/en.json
The common translation contract removes named collapse and expand keys. It adds copy-link and copied-state keys.
Locale namespace alignment
i18n/locales/*.json
Locale files remove named collapse and expand entries and add empty placeholders for several translation namespaces.
Accessibility validation
test/nuxt/a11y.spec.ts, test/nuxt/components/Package/Versions.spec.ts
Tests cover the heading button, expansion state, controlled content, accessible section-link naming, subtitle rendering, and the updated expand-button selector.

Explanation

The pull request includes unrelated locale changes. Many locale files add empty placeholders for features such as dependency statistics, sponsors, keyboard shortcuts, themes, trends, and comparison facets. These changes do not support issue #1392. The removal of the old collapse keys and addition of the two section-link keys are relevant.

Exercise the section-link copy path.

The test only checks the button label. It does not click the button or assert that the clipboard receives the current URL with #test-section. A regression in copySectionLink could therefore pass while copied section links no longer target the section.

Suggested fix

       const component = await mountSuspended(CollapsibleSection, {

         .find(b => b.attributes('aria-label')?.includes('Dependencies'))
       expect(linkButton).toBeDefined()
