/* ==========================================================================
   Mandate Studio — design system
   Layout concept: liquid-glass surfaces floating over a deep blue-green
   black canvas (dark-first), mirrored to a cool mist-white light theme.
   One accent family (blue into green, cyan where they meet), one display
   face (Archivo Expanded Black), one UI face (Plus Jakarta Sans).
   Glass, pills and radii follow the Roletrips system.
