Index-seed prompts carry the vertical they were written for. Other prompts (extension captures, people's runs) take the vertical their closest index-seed prompts agree on; 12 prompts didn't match any vertical closely enough and aren't shown. The numbers are rebuilt every 15 minutes. Search the index to find anything by keyword.
