# ResolutionFlow Design System Implementation Guide

## Overview
This guide provides everything needed to implement the new monochrome design with subtle icon accents across the entire ResolutionFlow application.

## Design Philosophy
- **95% Monochrome**: Pure black backgrounds, white text, transparent card overlays
- **5% Color**: Subtle colors ONLY on functional icons
- **Inspiration**: Plasma + Aspect templates (minimalist, modern, enterprise-grade)
- **Key Principle**: Restraint and sophistication over flashy gradients

## Implementation Checklist

### Phase 1: Global Styles
- [ ] Update background color to pure black gradient
- [ ] Set font-family to Inter
- [ ] Add subtle radial gradient overlays

### Phase 2: Component Updates
- [ ] Header/Navigation
- [ ] Hero sections
- [ ] Search bars
- [ ] Stat cards
- [ ] Active session cards (Bright Glow)
- [ ] Tree/item cards
- [ ] Buttons (primary & secondary)
- [ ] Forms/inputs
- [ ] Modals
- [ ] Empty states

### Phase 3: Icon Colors
- [ ] Map all icons to appropriate colors
- [ ] Keep time/clock icons gray
- [ ] Add category colors to tree icons

### Phase 4: Polish
- [ ] Add hover states to all interactive elements
- [ ] Test backdrop-filter blur support
- [ ] Verify contrast ratios for accessibility
- [ ] Test on dark displays

## Notes for Claude Code

1. **Preserve existing functionality** - Only change visual styling, not logic
2. **Use Tailwind classes** - Avoid custom CSS where possible
3. **Keep shadcn/ui components** - Just reskin them with new colors
4. **Test incrementally** - Update one component type at a time
5. **Icon mapping is critical** - Different tree types get different icon colors

## Questions to Resolve

1. Should all buttons use the same white style, or do you want variations?
2. Do you want the subtle radial gradient overlays, or pure black background?
3. Should stat cards always show trend indicators (up/down arrows)?
4. Any specific components that should NOT follow this design?
