Cross-Platform Jewellery eCommerce Theme

I’m building an imitation-jewellery store and need a custom theme that works out of the box on both Zoho Commerce and Shopify. The reference look is https://www.suwarnikaajewels.com, but with a clearly Traditional and elegant aesthetic throughout typography, palette, and iconography.

The theme must be coded so the same design assets and layout logic can be packaged as:
• a Shopify theme (Liquid, sections, JSON templates)
• a Zoho Commerce template (Drag-and-drop blocks, custom HTML/CSS)

Core pages to be included:
• Homepage
• Product listings / collection grid
• Contact-us page
• Any additional utility pages required for a smooth checkout flow

Homepage elements I want ready for easy merchandising:
• Featured products spotlight
• Customer testimonials slider
• New arrivals carousel
• Best-sellers grid
• Collection-type showcase

Please deliver clean, responsive HTML5/CSS3, semantic markup, and clear instructions on how to install or import the theme into each platform. All imagery and copy can be placeholder; I’ll swap in the final content later.

Once the theme is live on a test store in both ecosystems and mirrors the reference site’s speed, layout, and aesthetic fidelity, the project will be considered complete.
