/* ================================================================
   WGC Base CSS v2.0.0
   Shared stylesheet for all WoT: HEAT content pages
   Design principles (from art review 2026-03-25):
     A. Yellow is a verb — reserved for buttons/CTAs only
     B. Restraint is polish — hierarchy via size/weight, not color variety
     C. Density signals professionalism — compact, uniform layouts
   Changes from v1.0.0: see CHANGELOG.md v3.0.0
