/* ==========================================================================
   84 City — Design System v2 « produit » (2026-08-07)
   Inspiré de GitHub (Primer dark) / Nitrado : retenue, densité, système.
   - Une seule couleur d'accent (bleu), surfaces plates, bordures 1 px
   - Rayons discrets (6/8/10 px), zéro lueur / dégradé / flou décoratif
   - Typographie Inter (UI) + Space Grotesk (titres) auto-hébergées
   - Données en monospace, transitions 150 ms sur hover/focus uniquement
   Chargé APRÈS le <style> inline de chaque page : ses règles priment.
   Logo 84 City inchangé.
