Research: replace word-art sprites with styled text headings, update content

- Row 1: "3D / puzzles" (black/teal text, replacing sprite image)
- Row 2: "Faster / RNA structure / determination" (High-throughput → Faster)
- Row 3: "Rational / RNA design / & videogames" (RNA → Rational)
- Row 1 body: updated to mention CASP, RNA-Puzzles, Kaggle competitions
- Row 2 body: "in close collaboration with expert biologists at Stanford" → "and accelerating RNA cryo-EM"
