Poulpe (Silver Surfer deploy)
183bb0691d
Interpole en temps réel bg/ambient/fog entre palette de surface (teal lumineux y=55) et palette abyssale (bleu-noir y=-40). Fog density augmente en plongée (0.02 → 0.055) pour renforcer la sensation oppressante des grandes profondeurs. Courbe smoothstep pour transition organique.
