   - em : UNDERLINE PLUME lent 1.5s (vs barricade / cartouche)
   - meta : PLAQUE GRAVEE rotation -1deg (vs HUD / terminal)
   - bloc signature : COMPTEUR 30 ANS gigantesque + LIGNE
     1995-2025 qui se trace (vs schema SVG / scanner)
   - prose : drop cap editorial + fade lent
   - reconnaissance : underline qui scelle CF Summit
