   Custom CSS layered on top of Tailwind utilities. Implements the
   Apple-style "Liquid Glass" look: translucent panels, backdrop blur,
   soft gradient lighting, and fluid micro-animations. Dark theme by
   default, mobile-first. Brand palette is defined as CSS variables so
   it can be themed from one place.
