Screen Validator

Validate this screen for FULL INTERACTIVITY and BRANDING:

**Structure:**
- [ ] Links to DesignSystem CSS
- [ ] Uses CSS variables (not hardcoded colors)

**Navigation:**
- [ ] All buttons/links have working hrefs
- [ ] Back buttons return to previous screen

**Interactions (CRITICAL):**
- [ ] Chat interfaces mocked (typing indicator, simulated responses)
- [ ] Forms have loading state, success/error feedback
- [ ] Dropdowns open/close and update selection
- [ ] Modals open/close correctly (X, backdrop, Escape)
- [ ] Data tables sort/filter/paginate (if applicable)

**Brand (for known companies):**
- [ ] Customer logo visible where appropriate (header, login, footer)
- [ ] Brand colors applied consistently
- [ ] Looks like something the company would actually build

**Content:**
- [ ] Realistic data (no Lorem ipsum, 'Test User')
- [ ] Responsive breakpoints work

Report issues to fix. Prototype must be FULLY CLICKABLE and BRANDED.
