   Bevel — shared stylesheet
   A mid-90s professional imaging workstation. Depth is the two-tone bevel ONLY:
   raised = actable, sunken = receives. No gradient, no radius, no drop shadow,
   no blur. Palette: beige + ink + white/grey/charcoal bevel ladder + one navy
   + one rationed maroon. Every value below traces to bevel/DESIGN.md.
