/* ============================================
   Reorder Engine Styles

   Contains automatic reorder system styling:
   - Tab navigation for different reorder views
   - Stock movement tracking and history
   - Reorder suggestions and recommendations
   - Supplier grouping and ordering summaries
   - Activity logging with modal statistics
   - Real-time stock level indicators
   - Responsive design for mobile

   Dependencies: core.css (variables), components.css (buttons, modals)

   Cleanup Notes:
   - Replaced all non-standard variables:
     * var(--surface) → var(--bg-card)
     * var(--surface-dark) → var(--bg-dark)
     * var(--input-bg) → var(--bg-input)
     * var(--accent-color) → var(--accent-success)
     * var(--warning-color) → var(--accent-warning)
   - Added CSS variable aliases in core.css for backward compatibility
   - Unified all color values using standard palette
   - Removed duplicate modal definitions
   - Used consistent color scheme (green = success actions)
