Standalone, any order, each a full edit/recompile/redeploy/call cycle:
- Guided build: Greeter, line by line
- A change counter and reset
- An owner-only emergency reset
- A second event
- A length cap and revert handling
- Tracking the longest greeting
The guided build is required before the project; 01-05 are optional practice reps, each a full cycle on the same contract.
