VishalSurti/RealmWeaver ? reverse-engineered prompt

Build me a tabletop RPG app called RealmWeaver that helps people run a campaign with an AI dungeon master feel, but with consistent rules and a saved world that keeps going between sessions.

I want players and a game master to be able to create a campaign, make characters, track quests, inventory, stats, locations, and past events, then come back later and pick up exactly where they left off. The game should feel guided by AI, but the core mechanics need to stay deterministic so dice rolls, combat, skill checks, and other outcomes are fair and repeatable.

Make the experience simple and friendly, with a clean interface for starting a new game, advancing turns, and reviewing the campaign history. Save everything persistently so the story, characters, and world state do not reset. If you need to look up current docs or best practices for any tools, do that. Focus on making a polished working prototype that feels playable right away.
