Verify slow WebGL animation cycles by patching performance.now and in-scene fast-forwards

Problem: a three.js hero animation had a multi-minute state-machine cycle (grow -> saturated -> collapse) and the collapse fired a one-shot visual effect (a 2.5s leaf gust). Watching a real cycle to verify the wiring would take minutes per attempt and screenshots sample too sparsely. What worked:…
