Stores now automatically validate Liquid templates upon saving, surfacing syntax errors, missing layout tags, and unreferenced assets directly in the theme editor. Additionally, published themes track runtime issues such as rendering errors, slow templates, and missing assets, reporting them as alerts via the API. Template endpoints now include a `warnings` field to help you diagnose and fix theme issues quickly without blocking your workflow.
