Shopify Website Replication of Rudraksha-Ratna

I want to create a replica of [login to view URL] using the Ella theme on Themeforest [login to view URL] This replica will be built on Shopify The main development effort is on the product page, please see these carefully - there are several levels of nested logic: [login to view URL] [login to view URL] 1. The non-negotiable requirement is to build this custom product page (identical to the URLs above) in Shopify without 3rd party plugins. 2. Batch uploading of products via CSV - You will be responsible for creating the CSV format and ensuring the data is uploaded successfully. My team will be responsible for populating the CSV. 3. Design and other features will be heavily used from the Ella theme on Themeforest. 4. 15 Static pages - content and design will be provided by my team. This is a unique project because the requirements are crystal clear - as we are replicating the product page features verbatim. Please answer the questions below in your proposal - these cannot be answered by an AI LLM because it requires a proper human analysis. Have you looked at [login to view URL] - and all the nested logic? Please see URL and attachments for reference. There are several customisations - will you be able to replicate the functionality of variant images? Without reloading the full page? Because it has several variants - Shopify has a restriction of maximum 100 variants - what will be your approach to develop it? In some cases the variants can cross 100. What will be your approach to upload these products with multiple variants via CSV? A private app? GraphQL? or RESTAPI? When a gemstone with its multiple variants is selected and added to cart, will it be one line item or several? The Energisation section also has an upload image function - where will this be stored and displayed in the order / Shopify for the Admin?
