bench: JSPI vs asyncify A/B — harness + results Adds pcbnew-large-perf.spec.ts (PERF_LARGE-gated: repeated cold loads, vme-wren/jetson opens, rAF + distinct-glcanvas-frame FPS under throttle, wasm/JS heap checkpoints), fetchIntoMemfs + openAndWait/sampleMemory/ measureFpsDetailed perf-utils, dual 9.99+10.0 config seeding in pcbnew.html so foreign-branch builds boot wizard-free, and the full benchmark report + raw data under docs/features/async/migration-evidence/. Headlines: wasm 94 vs 113 MB raw (18.6 vs 36.7 MB gzip), post-link tail 1.6 s/49 MB vs 63 s/6.1 GB per build, cold load −40 %, 27.7 MB board open −45 %, real redraws +68 % at 4× throttle, boot heap −31 %.

bench: jetson FPS battery — both backends saturate at 80.9 MB scale Parameterizes the throttle-sweep FPS battery (fpsBattery helper) and adds a jetson-agx-thor run: asyncify raf 2.1-5.3 / distinct 0.2-0.8 vs JSPI raf 1.9-5.0 / distinct 0.1-0.7 — indistinguishable. Suspension overhead is a per-event-loop-turn cost; at hundreds of ms of GAL work per frame it stops discriminating. vme-wren (~27 MB) remains the discriminating size class.
