   AstonLegacy — single.css
   PAGE ARTICLE — single.php  (is_singular('post'))

   Refonte « long-read cinématique » + design system mutualisé :
     • hero plein écran qui rétrécit au scroll (scroll-driven CSS)
     • barre de progression de lecture (100% CSS, animation-timeline:scroll())
     • plaque hero en DOUBLE verre (.al-glass + .al-glass__panel)
     • colonne centrée + sommaire (gauche) & partage (droite) STICKY
     • liens in-text « redessinés » (effet Aaron Iker, CSS pur)
     • modèle lié en bande pleine largeur (.al-btn--gooey-white)
     • « À lire aussi » en cartes poster (langage .rev-card)

   Contrat toc.js INCHANGÉ : #article-content · #toc-items · #sidebar-toc
     .sidebar-toc__item / __num / __text / --active
   Or « selon la situation » (WCAG) : FOND CLAIR → gold-deep ; SOMBRE → gold.
