Three inline CSS/SVG animations demonstrate key concepts:
- Hero: 3-funnel flow diagram with animated particles, threshold lines,
rising/falling fill levels, and flowing dashed edges with % labels
- How It Works: Sankey-style river view with multiple flowing bands
showing Revenue/Grants splitting to Team A/B/Reserve
- Funnel Model: animated water level cycling through overflow/healthy/
critical zones with overflow arrow that appears at peak fill
All animations are pure SVG/CSS (zero external assets), responsive,
and hidden on screens <480px. Replaces the static funnel metaphor
text block with a side-by-side animated funnel + zone descriptions.
