/* ===========================================================================
   GoGuru admin dashboard — dark bento theme

   Colour discipline (validated with the dataviz palette validator against
   the #16151d surface):
     • DATA MARKS carry meaning -> one hue only (--data). A per-tutor bar
       chart is magnitude of a single measure, so every bar is the same
       colour; ramping bar colour by size would double-encode length.
     • STATUS colours are reserved and always ship with a text label, never
       colour alone (their CVD separation sits at the floor).
     • GRADIENTS encode nothing — they're atmosphere — so they stay bright
       and playful per the reference kit.
