UniverseTheme

label
Type: string
required

The theme name, and the exact string that goes in Universe.Theme.
ticker_count
Type: number
required

Securities this theme contributes to a scan universe: core + satellite assignments. NOT num_tickers from /api/v2/stocks/themes, which is core-only — expect the two to differ.
color
Type: string

Stable hex colour, inherited across runs where membership persists — the same colour the theme performance charts use. Optional.
short_label
Type: string

Abbreviated name for dense/small-screen contexts. Absent on classification runs predating the field, so always fall back to label.
