Mobile Theme Layout Repair for Merchants
The Opportunity
An app that scans a Shopify theme for mobile breakage after AI-assisted or custom CSS edits and suggests safe fixes. It would help merchants quickly identify which theme rules are causing mobile layout issues and apply reversible overrides.
"The store's mobile view is broken after repeated customizations, and the merchant cannot reliably identify the CSS/theme changes causing the issue."

Detailed Analysis
Proposed Solution
Provide automated theme diffing, mobile layout diagnostics, and one-click rollback or safe override suggestions for common breakpoints and broken containers.
Target Audience
Shopify merchants who customize themes, especially non-technical store owners using AI tools or freelancers
Competitive Landscape
Theme Check, HeyMerchants theme support tools, various Shopify theme optimization apps, generic developer tools and agencies
Implementation Notes
Build a theme asset scanner that compares current CSS/liquid against prior versions, detects risky properties like width:min-content on mobile, previews responsive breakpoints, and offers guided fixes with undo/history. Use Shopify theme app extensions or admin app UI, but keep changes scoped to theme files and provide backup/restore before edits.
