/* Liquid glass: one layer on top of styles.css that gives the whole platform a translucent, light-refracting look.
   Surfaces become frosted glass (blur + saturation + a bright top edge) floating over a soft colour field that follows the brand.
   Everything is driven by the same tokens the app already uses (--surface, --border, --shadow, --radius), so every screen picks it up.
   Safe fallbacks: solid surfaces when the browser has no backdrop blur, or when the person asks for less transparency or more contrast. */
