Add new pages in Shopify, without using our theme's styles and structure

Topic summary

Goal: create internal-only Shopify pages that do not inherit the store’s theme styles or layout, so a designer can apply a completely separate design for a warehouse manager.

Steps taken: created a new theme page template via Edit Code; inserted custom HTML, CSS, and JS into that template; created a new Page in the admin and assigned it to the custom template.

Issue: despite using the custom template, the page still adopts the existing theme’s global styles and structure, overriding the intended standalone design.

Request: guidance on how to bypass or exclude the theme’s styling/structure for specific pages (e.g., a truly blank template or other method) so the page renders only the custom code.

Status: no solution yet; assistance requested, discussion open.

Hell there, on our shopify site we have a theme installed. We want to add certain pages into the store for internal purposes exclusively (for our warehouse manager). These pages must remain devoid of any predefined styles or structure, as our designer will handle their design separately. So, I crafted a new theme template page within the “Edit Code” section. Subsequently, I inserted the HTML, CSS, and JS code into this page template. Upon returning to the main online store menu, I proceeded to create a new page, then linked it to the aforementioned theme page template. Despite these efforts, the page continues to adopt the styles and structure of our existing theme, deviating from our designer’s design. Any assistance in getting around this issue would be greatly appreciated.
