what is superwhite fr?

Superwhite is described as an HDR PQ image tool that runs fully in the browser, with no server processing needed. The stated idea is to make an image glow brighter than plain white by working with the PQ color profile used in HDR content, which is the same technology behind HDR photos and videos looking brighter on newer phone and laptop screens. The README for this repository is unusual: instead of explaining how the tool works or what a user does with it step by step, it reads as a launch checklist for the project's creator, listing the remaining setup tasks before the site goes live. It covers pushing the code to a repository, deploying it on Cloudflare Pages, buying and connecting a custom domain, setting up an email waitlist form for a planned paid tier called Superwhite Pro, and adding basic site analytics. Because of this, the README does not describe the actual image conversion process, what file formats are supported, or how the interface works. The checklist does reveal a few things about the product's direction. There is a verification step where the creator is meant to convert an image, download it, post it to LinkedIn, then download it back and check with a tool called exiftool that the image still carries its PQ or Rec.2100 color profile information, confirming the glow effect survives being uploaded and downloaded from a social platform. Planned future work, explicitly marked as not needed for the initial launch, includes a paid tier gated by a license key, batch processing multiple images at once using a client-side zip library for an Agency plan, and an Ultra HDR export option aimed at Instagram, planned as a version two feature. Overall, this repository documents deployment steps rather than product usage, and a non-technical reader looking to understand the tool itself would need to visit the live site rather than rely on this README.
