Create templates/public/head.php accepting $pageTitle and $extraCss (array of
stylesheet hrefs), mirroring the existing templates/admin/head.php pattern.
The partial emits: DOCTYPE, <html lang=fr>, charset/viewport meta, favicon,
modern-normalize, common.css, any extra CSS links, and the dev-only live-reload
script. The live-reload snippet was previously copy-pasted verbatim into all
five public pages.
Updated pages:
- public/index.php ($pageTitle='Posterg', $extraCss=['assets/main.css'])
- public/search.php ($pageTitle='Répertoire – Posterg', search.css)
- public/tfe.php ($pageTitle=thesis title + suffix, tfe.css)
- public/apropos.php ($pageTitle='À Propos – Posterg', apropos.css)
- public/licence.php ($pageTitle=DB title + suffix, apropos.css)
tfe.php: removed redundant htmlspecialchars() call on $pageTitle (the partial
applies it); licence.php: renamed conflicting $page variable to $dbPage to
avoid collision with the shared $pageTitle expected by the partial.
All syntax checks and test suite pass (4/4).
