/* =========================================================
   BASE Dance Studio — design system
   Subject: k-pop & street dance studio (Brazil).
   Palette pulls from the rehearsal room: marley floor, studio
   mirror, and the two colors of gaffer spacing-tape dancers
   use to mark the floor. Type pairs a condensed signage face
   (posters, crew branding) with a clean geometric body face,
   plus a mono face for counts and cue sheets.
