cugdl-apps/asignacion-grupos ? reverse-engineered prompt

Build me a simple web page for assigning groups and classrooms for a university schedule.

It should load the JSON files in this folder, show the available classrooms, professors, categories, and the current group data, and let me quickly see or update who is assigned to what. I want it to feel like a practical internal tool, not a fancy app, so keep it clean and easy to use.

Use the images already included for basic branding, and make the main screen centered around the assignment data with clear tables or cards. If there’s historical professor data, make it easy to view for reference. The page should work as a single HTML file and read the local JSON files in a simple way that makes sense for a browser based app.

If anything needs a current best practice or a small helper library, look up the latest docs online first.
