/* ==============================================
   RTOFlow Context Colour System
   ==============================================
   
   Purpose: Provide visual consistency across related pages
   by using colour-coded accents and navigation buttons.
   
   Colour Assignments (in sequence):
   1. Compliance Library  → Amber/Gold (#f59e0b)
   2. System Library      → Sky Blue (#0ea5e9)
   3. RTO Resources       → Orange (#ea580c)
   4. (Future) Training   → Green (#10b981)
   5. (Future) Assessment → Purple (#8b5cf6)
   6. (Future) Reports    → Pink (#ec4899)
   
   Usage:
   - Add .context-{name} class to page container
   - Use .context-btn-{name} for navigation buttons
   - Colour band appears as top border on main content
