When the stack builder picks it
The builder reads each job's rules from the top and takes the first step whose conditions hold and whose plan fits the money left. Grammarly is named in these steps:
- Copywriting, step 2 of 4, when you chose that way of working: Pro ($30/mo).
The rules are public in stack-rules.json, and how the stack builder scores explains the tie-break.
