   blog-article.css -- Feature Blog Article (F7 art-*)
   Portage V6a.3 depuis v6/VAGUE_6_MOCKUP_v3.html (bloc <style> L7-L1639)

   13 zones spec section 9.1 + Zone 13 transitoire #101 (.art-tag restreinte,
   supprimable V6a.5 apres refonte template). Tokens A1/A2/A3 V6a.1
   (commit ec7ec63) consommes en var() exclusif.

   Convention : header ASCII + zones numerotees + tokens-only + parity
   .theme-dark ET @media (prefers-color-scheme: dark). ASCII pur stricte.

   Dettes tracees :
   - #90 remplacement ancien token border (nom historique FCD34D light /
     rgba dark) par --accent-warm-surface-border applique partout dans
     ce fichier (alignement V6a.1 #89).
   - #92 RESOLU V6a.4.6 : nommage BEM case-block + pitfall-block
     (alignement partials V6a.4.5a, mockup v4 reporte #128a).
   - #102 defer loading : blog-article.css herite du defer media="print"
     de static/app.css L31 via chainage @import. Impact V6a.3 nul
     (cascade inerte), impact V6a.3.5 critique (FOUC potentiel).
     Diagnostic DIS-defer obligatoire V6a.3.5-pre.

   Consommateurs :
   - Templates : templates/blog_article.html (post V6a.3.5 extraction
     corps app.css des 54 classes .art-*). V6a.3 : cascade inerte
     (app.css corps WINNER sur specificite egale + ordre import).
   - JS : static/script.js reading-progress + TOC highlight (scope
     template, pas ce fichier).

   Version : V6a.3 initiale (baseline NEW Playwright).
