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. v0 is named in these steps:

App builder, step 2 of 3, when less than $20 is left for it: the free plan; the step also names Lovable and Bolt.new, and the best score takes it.
App builder, step 3 of 3, otherwise: Plus ($30/mo); the step also names Lovable, Bolt.new and Replit, and the best score takes it.
Websites and landing pages, step 3 of 5, when you also ticked app builder: Plus ($30/mo); the step also names Lovable and Bolt.new, and the best score takes it.

The rules are public in stack-rules.json, and how the stack builder scores explains the tie-break.
