Shopify Custom Grid Layout Migration

I’ve upgraded our Shopify store to the newest Broadcast theme and now need the custom grid-based layouts from the previous theme brought across and fully functional within 1–2 days. All the Liquid, CSS and JavaScript for these grids already exists in the old theme files; it just needs to be transplanted, refactored where necessary, and tested so it meshes cleanly with Broadcast’s structure and settings.

The grids to migrate cover:
• product listings
• blog articles
• featured collections on the home page
• standard collection pages and category views

Acceptance will be based on:
• identical grid behaviour and styling in the new theme on both desktop and mobile
• use of native Broadcast theme settings wherever possible (no hard-coding that blocks future updates)
• zero impact on checkout, page speed or existing apps

You’ll get theme access plus a ZIP of the old code immediately. If you can adapt Liquid snippets, sections and JSON templates quickly and push the finished work to a preview link for sign-off within 48 hours, let’s move forward.
