Shopify Product Page Customization

I need a Shopify theme specialist to fine-tune the product page template so my descriptions and specifications stand out clearly and look consistent across the store. The work is entirely theme customization; the rest of the site is already set up and running smoothly.

Here’s what I’m after:
• Re-structure the product description area using Liquid so I can break content into clear headings, bullet points, or tabbed sections without touching code every time I add a product.
• Add a dedicated specifications block that can pull data from metafields for quick updates later.
• Make sure the new layout inherits my current typography and colour settings, remains fully responsive, and loads just as fast as the existing theme.

I’m happy with the current images, pricing layout, and navigation, so please focus only on the description and spec portions of the product pages. Familiarity with Liquid, JSON templates, and Shopify’s theme editor is essential.

Deliverables:
1. Updated product.liquid (or equivalent JSON template) and any supporting snippets/sections.
2. Brief written guide showing where and how to edit descriptions or specs in the admin.

Once everything is implemented I’ll test on desktop and mobile; if the content displays exactly as designed and no existing styling breaks, the job is complete.
