Quick decision aid
- "Where does this state live?" →
40.01 - "Should this be a new file?" →
40.02 - "Can A import B?" →
40.03 - "This hook is getting complex" →
40.04(TS) - "Should I make a factory/class for this?" →
40.05(TS) - "This file is 1000+ lines, how do I split it?" →
30.04(closure monolith decomposition)
