Amasty Preorder Integration

[steveberrill]

I recently worked through a tricky conflict between all product types and Amasty Preorder under the Breeze theme.

The main issue was that the bundle summary wouldn’t render correctly in production mode, and the product gallery layout broke when excluding Breeze via the "Disable Breeze for specified URLs" config.

After extensive debugging, I resolved the problem by:

• Keeping Breeze enabled for bundle product pages.
• Re-enabling bundle.phtml from Magento_Bundle in my theme to fix $.mage.amastyPreorderBundle is not a function errors.
• Ensuring my theme inherits correctly from Swissup/breeze-evolution and not mixing Luma scripts (which was causing layout issues).

Once this was done, bundle summary, product gallery, and Amasty Preorder all worked correctly in production.

Just sharing in case it helps someone else facing the same integration headache.

I have shared theme overloading files rather than creating a module
