- Add roi_output_hero_critical_css() function to inject CSS in <head>
- CSS now loads BEFORE hero HTML renders, preventing CLS
- Update min_height from 120px to 260px to match actual content height
- Update title_min_height from 3rem to 3.5rem
- Add responsive breakpoints for mobile (200px min-height)
This fixes CLS in Lighthouse Lab tests (was 0.265, now should be ~0.01)
