Start the "Build Until Green" loop.

Goal: production build succeeds
Max iterations: 10
Between iterations run: npm run build
Exit when: npm run build exits 0

Step 1: Run the build. If it fails, fix the first error, then repeat until green.

Self-pace this loop. After each iteration, run the check command, read the output, and only continue if the exit condition is not met. Stop when the exit condition passes or max iterations is reached. Give a short status update each pass.
