I am gatekeeping this workflow but I have a bunch of Codex resets I need to use before the end of the month, so I got a draw, proof, review feedback loop going with GPT-6 Astra that is doing a really good job adding missing Hebrew and Bold drawings to Virtua Grotesk. I only use Runebender to clean up the last 5% of the work, and I think with better context files I can get that down to 1%.
