Added to Cart Condition#198

Add a feature to change the state or style of an element depending on whether a specific product has been added to the cart or not. For example, it would be great to:

• Show a button labeled “Add to cart” when the product hasn’t been added yet.
• Then switch to a different state — such as “Added”, a check icon, or even a disabled style — once the product is already in the cart.

This kind of conditional logic or dynamic styling would make it much easier to guide the user and reduce friction in multi-product configurations or bundles.

If there’s any existing workaround for this (like visibility conditions or dynamic components), I’d be happy to explore it. Otherwise, I hope you’ll consider this for your roadmap — it would unlock a lot of flexibility in customizer experiences.
