   ----------------------------------------------------------------------------
   Rules this file follows, deliberately:
     · One accent, and it is the reading itself. Everything else is neutral.
     · Hairlines and one material. No card-on-card, no decorative gradients.
     · Type does the hierarchy: few sizes, big jumps, tight tracking on display.
     · Motion only on state change. Nothing loops in the background.
