Detailed Description

Baseline micro-benchmark for the structured-editing design doc.

Measures the performance of operations that the structured-editing M5/M6 incremental fast path is designed to replace. The numbers from this harness ground every "needs measurement" row in the Performance table of docs/design_docs/0049-structured_text_editing.md.

All benchmarks use representative SVG inputs - not contrived worst-cases

• so the baseline reflects what editors actually encounter. Worst-case benchmarks (10k-element SVG, 500-command path) are included as separate entries so the gap is visible.

Usage:

bazel run -c opt //donner/benchmarks:structured_editing_perf_bench -- \
    --benchmark_min_time=0.5s
