The details make the difference.
Performance
Efficiency designed into the critical path. Measure first, then make every operation count.
Reliability
Design for interruptions, recovery, and the conditions that happy-path demos leave out.
Correctness
Make guarantees explicit. Verify the boundaries, not just the expected outcomes.
Developer experience
Powerful ideas deserve clear interfaces. Make the right path approachable.
