Performance Regression Control

Detect when features, assets, apps, or content degrade storefront speed or interaction behavior.

Regression watch

Baseline → change → compare

Performance, layout, interaction, and storefront behavior are compared against a known-good state.

Signals

Page weight

Layout overflow

Interaction errors

Find the release that introduced the change.

Apps, media, scripts, sections, content, and theme code can all move performance. The response is to isolate the regression—not redesign everything.
