Device-only state

League joins, lineups, mock drafts, picks and preferences stay in this browser. Nothing is written to an account or production service.

Replayable evidence

Current entity or calendar layers are labeled separately from last-completed performance baselines. Data Health exposes sources, gaps and comparison limits.

Rights-safe visuals

Product marks are repo-owned. Editorial art is original prototype art with no real people, team or league marks, sponsor branding or embedded text.
