ComboHeatBackground
Reactive background that lerps between a "cool" and "hot" color as heat rises (IDEA-08) — the caller computes heat from whatever combo/ streak mechanic it has (e.g. min(1.0, comboCount / 10)); this widget has no idea what a "combo" is, matching VictoryCardTemplate's convention of taking caller-computed values rather than inventing game-specific mechanics.
