PERF3: pumpBench.test.ts pins pump()'s pipeline cost — 0.43ms @5k items,
1.47ms @20k (median) — negligible at a few events/sec, so the
count+pointer rewrite of the core queue is declined as risk without
reward; the benchmark stays as a 5ms regression tripwire.
PERF6/L162: closed as documented-by-design (virtualization bounds
mounted thumbs; a theme prop conflicts with PERF5's stable renderer).
