   ALVIA — Habillage Aurora du blog & pages éditoriales legacy (smoke-test).
   Chargé APRÈS /styles.css → surcharge les classes legacy. Reprend les tokens,
   la typo (Bricolage/Onest) et le langage flat du site-vitrine (Aurora).
   Le header/footer legacy sont remplacés par un chrome préfixé .av-* (markup
   patché dans le HTML) : self-contained, aucun conflit avec styles.css.
