/* Poltergate cabinet design system — "séance".
   A midnight console on the left, a quiet neutral desk on the right. One flat jade green (no gradients, shine or glow —
   the owner's call) marks focus and the current place; main buttons are black (white in the dark theme); amber means
   asleep, coral trouble. The sidebar stays dark in both themes; light follows the system by default, the dark theme
   is graphite night.
   Icons are duotone: a line drawing over a soft tinted fill (class "d"). */
