/* ============================================================================
   Brain Workshop — Design System (Synapse-based, B1.5)

   Source: SuperDesign / Synapse (Zhou Jason)
   https://app.superdesign.dev/library/synapse

   Adaptations from base Synapse (per William's PMSuite reference):
   - Sans-serif headlines (Inter Tight) instead of Instrument Serif
   - Multi-color category pill system (PMSuite-style)
   - Slightly less harsh deep navy (#0a0a0f) instead of pure black (#030303)
   - Rounded pill button family (NOT brutalist 0px corners)
   - Friendly, approachable SaaS-feel over premium-luxury

   Applies to both /brain/admin/* (admin_ui) and /brain/dashboard/* (S13).
