- Convert .apropos-toc <nav> to <details class="toc" open> in all three templates
- Add caret-down icon to summary (visible only on mobile via media queries)
- Desktop (≥768px): sticky sidebar via CSS grid, force-open via pointer-events:none, hide caret
- Mobile (≤767px): single column, collapsible TOC with rotating caret, margin-top below search bar
- Rename .apropos-toc-link to .toc-sidebar-link
- Merge 900px and 600px breakpoints into single 600px mobile media query
- Rename apropos.css → content-page.css; update 3 controller references
Unify the three public pages (à propos, charte, licence) onto a single
grid layout (.page-content) with sticky TOC sidebar, replacing the old
separate / / markup.
- Merge about.php, charte.php, licence.php templates into shared
.page-content / .content-section structure
- Add CommonMark HeadingPermalinkExtension for stable heading anchors
- Use SlugNormalizer for TOC links so they match rendered heading IDs
- Standardize link styling across content blocks: bold black, accent on
hover (consistent with global link style)
- Fix code block wrapping: use pre-wrap instead of pre, constrain grid
columns with min-width:0, auto scrollbar
- Fix apropos page grid placement: force content-section into column 2
so contacts and credits stay in the content area, not the sidebar
Also includes accumulated WIP changes:
- Header gradient: hardcoded purple-to-green (replaces CSS variables)
- Search placeholder font
- Duration field: replace minutes/sec/heures with h:m:s time inputs
- TFE file optional for formats 1,4,6 with client-side JS toggle
- Licence form: em-dash to hyphen, details/summary classes
- Pill search: block Enter key form submission when no results
- Draft autosave: remove CSRF rotation (broke concurrent FilePond uploads)
- Language pill: clear hints for excluded main languages
- Search results: gradient placeholder cards for items without covers
- TFE display: format durée values as XhYm instead of decimal
