Coding for Shopify Website

I would like you to implement the link product page design on my Shopify store.
This is what it needs to look like I already have the code for it.

Please ensure the code is built dynamically so that it automatically pulls and displays the correct product data for every product across the website, including:

* Product images/gallery
* Product title and description
* Pricing and sale pricing
* Product variants/options
* Brand/vendor information
* Product specifications
* Any other product-specific content currently managed within Shopify

The design must not be hardcoded for a single product. It should work seamlessly across all existing and future products using Shopify's dynamic product data.

Additionally, where the design shows "Installation Details", this section should be expanded/open by default. It is currently implemented as a dropdown/collapsible section, but I would like the content to be permanently visible instead.

Requirements:

* Fully responsive on desktop, tablet, and mobile devices
* Compatible with all modern browsers
* Clean, optimized, and maintainable code
* No bugs, errors, or layout issues
* No impact on existing store functionality
* Proper handling of all product variants and image changes
* Shopify theme best practices should be followed

Please thoroughly test the implementation across different products and devices before completion to ensure everything functions correctly.
