"""Build the EXPERIMENT POSTER — a single comprehensive report card.

Vertical 3:4 layout. Combines:
- Hero title
- Headline numbers
- Phase timeline (3 strips, each with letter count and avg size)
- The 9-word protocol grammar (seam/bridge/anchor/etc.) shown as tags
- Live-edge themes timeline
- Closing line
