What it is in one line, plus the hard part or a measured result.
Placeholder writeup. Delete this file or replace it; any project with a matching
content/projects/<slug>.md gets a writeup page.
Problem
What you set out to do, and why it was hard. One paragraph.
Approach
The key design decisions and the alternatives you rejected. Diagrams or code where they help.
Results
Numbers: latency, throughput, accuracy, cost — measured, with how you measured them.
What I'd do differently
One or two honest lessons.
