/* Liquid Glass theme, hand-written (no CSS framework). Layering follows
   Apple's HIG Materials guidance: glass (translucency + backdrop blur +
   luminosity adaptation) is reserved for the FUNCTIONAL layer — sidebar,
   topbar, segmented controls — while content cards stay near-opaque
   standard material so data keeps full legibility. Light/dark are both
   deliberate palettes, swapped via html[data-theme] (set by app.js). */
