- Set the candidates. Name the contenders for the California's 23rd Congressional District (or keep the generic Democrat / Republican defaults). The map starts from the canonical mixed-grain 2024 presidential baseline.
- Apply a swing. Move vote share statewide, or by demographic cohort, with a slider. The map and the running tally recompute instantly.

- Roll up & share. Roll the result up to chamber control, then share the exact versioned scenario.
