History
How the AI Pics history keeps every run with its prompt, shape, seed, model and settings, the states of runs and pictures, retry and delete.
Every run is kept with its prompt, shape, count, seed, provider and model, and the state of each picture. A run is queued, running, done or failed. Reuse a run's settings for a new run, retry a failed one, or delete a run and its pictures for good.
A picture made by the Preview is made by an open page: if you queued a run and closed the tab, another open page of the workspace makes it, or it waits.
