The goal of this step

What I did
- [ first concrete thing ]
- [ second concrete thing ]
- [ third concrete thing ]
The tricky part
[ The one thing that actually cost time. Be specific and honest — this is the section readers remember. ]
# [ the handful of commands / code that matter — keep it copy-pasteable ]
Honest note: [ anything simulated, stubbed, or deferred at this stage — state it plainly. ]
Result
[ The concrete, verifiable win for this step, and what it unlocks for the next one. ]
