Methodology (v2 static injection): Each app's script was injected into a clean Shopify-shell page alongside Booster Page Speed. CPU execution time was isolated using V8 ScriptDuration delta — measuring only the app's code, not the optimizer's own overhead. 3 runs, median taken. Baseline = app alone; paired = app + optimizer running simultaneously.
