Vitti26/DnD-DM ? reverse-engineered prompt

Build me a simple web app for a D&D dungeon master that helps run a session from one place.

I want a clean interface where I can manage combat, keep track of initiative, health, turns, and basic encounter info, plus save and load session data so I can come back to it later. It should feel like a handy DM dashboard, something I can open during a game and use quickly without a lot of clicking.

Use the existing Next.js app structure and wire it up so the important data is stored properly, ideally with Supabase since the project already has schema and migration files for that. Make the experience polished and easy to use on desktop.

If anything is unclear, make reasonable choices and look up current docs online if you need to.
