   HERO — AURORE BORÉALE ANIMÉE  (couche décorative, index.html)
   ------------------------------------------------------------
   10 BANDES verticales étroites, légèrement inclinées, calées sur
   les rideaux réellement visibles dans islande-aurore-boreale.jpeg.

   PRINCIPE : l'effet est une MODULATION D'INTENSITÉ localisée,
   pas un déplacement. Chaque bande s'éteint (opacity ~.02) puis
   se rallume (opacity max) à son propre rythme.
     · SEULE opacity est animée → aucun mouvement d'ensemble
     · rotate() est STATIQUE (inclinaison du rideau)
     · le blur est STATIQUE : jamais animé
   Les durées sont 10 nombres premiers distincts : le motif global
   ne se répète qu'au bout de leur PPCM (des siècles), et deux
   bandes voisines ne sont jamais en phase.

   RÉGLAGES — ne modifier que les variables ci-dessous :

   --aurora-opacity-max ...... intensité générale (.20 défaut)
                               .12 = très subtil · .28 = marqué
   --aurora-speed ............ multiplicateur de durée
                               (1 défaut · 1.5 = plus lent)
   --aurora-blur ............. douceur des bandes (46px défaut).
                               ⚠ au-delà de ~60px les bandes
                               voisines fusionnent en nappe et
                               l'effet localisé disparaît.
   --aurora-blend ............ screen (défaut) · soft-light si ça crame
   --aurora-safe-x ........... demi-largeur de la zone protégée
   --aurora-safe-up / -down .. hauteur protégée au-dessus / en dessous
                               du centre du viewport
   --aurora-safe-fade ........ douceur du bord de la zone protégée

   ZONE PROTÉGÉE — pourquoi un rectangle et plus une ellipse :
   une ellipse à bord doux assez grande pour couvrir entièrement un
   bloc de texte large laisse fuir de la lumière dans les coins du
   bloc (mesuré : 9/255 sur le bord du titre) tout en éteignant
   presque toute la largeur utile. Ici le masque est l'UNION de deux
   dégradés linéaires : la lumière n'est coupée qu'à l'INTERSECTION,
   c'est-à-dire strictement dans le rectangle du texte. Les quatre
   bords du hero restent libres.
   Cotes calées sur les pixels de texte réellement rendus
   (accroche + titre + sous-titre), mesurés à 1440×900.
