/* ==========================================================================
   TRACKDAY BRAND — v3
   Governing idea: THE MARK STAYS FLAT, THE WORLD AROUND IT BECOMES PHYSICAL.
   Depth belongs to paper, board, ink, foil and light. Never to the mark.
   Palette and clear space come from brand/tokens.json (identity v1.2). The
   custom properties below are generated by site/build_v3.py — see the marker.
   Type (guidelines p.07):    Cinzel 600/500 display · Montserrat 400/500/600
   Tracking is taken verbatim from p.07 — see the .t-* classes.
