## Key Findings Summary

### The Opportunity

**The terminal is the most underrated UI platform of 2026.**

- ✅ Supports truecolor (16M colors)
- ✅ Mouse input and gestures
- ✅ Graphics protocols (sixel, kitty, iterm2)
- ✅ Hyperlinks (clickable URLs)
- ✅ Unicode and emoji
- ✅ Real-time streaming

**Innovation Gap**: Web UI has 15+ years of innovation. TUI has been stagnant since ncurses. We can bring React-like experiences to terminal.

### The Solution

**Textual Framework + Modern UX Patterns**

1. **Command Palette** (Ctrl+K) - Discoverability
2. **Real-time Dashboard** - Live monitoring
3. **Interactive Tables** - Sortable, filterable
4. **Visual Workflows** - Drag-drop builders
5. **AI Integration** - Natural language commands
6. **Better Error Handling** - Actionable messages

### The Implementation

**Time to First Prototype**: 2-3 days
**Production Ready**: 8 weeks
**Dependencies**: Textual + Rich + httpx (5MB)

## Questions?

**Common Questions**

**Q: Will this work on all terminals?**
A: Yes, Textual works on any modern terminal with truecolor support (99% of terminals).

**Q: Will this replace the CLI?**
A: No, TUI is complementary. CLI for scripts/automation, TUI for interactive use.

**Q: How big are the dependencies?**
A: Textual + Rich = ~5MB. Negligible impact.

**Q: Can I test TUI in CI?**
A: Yes, Textual has headless mode for automated testing.

**Q: What about accessibility?**
A: Textual has screen reader support. We'll follow WCAG guidelines.
