kmhuglen/azureblobcontainerbrowser ? reverse-engineered prompt

Build me a simple web page that lets me browse files in an Azure Blob Storage container using a SAS URL.

I want to paste in a SAS link with read and list access, then see the blobs in a table with the file name, last modified date, and size. If there are folders, I should be able to click into them and move around the container like a file browser. I also want to be able to download individual files directly from the page.

Please include clear error messages if the SAS link is wrong or if access is blocked by CORS or firewall settings, and show a short help section that explains what needs to be set up in Azure for it to work. Keep it lightweight and browser based, with a clean single page layout that works well as a static site. If you need to check current Azure docs or API details, look them up online first.
