/* Probability slider — tool-specific styles.

 * This file does: the prompt chips, the live bar chart of next-token
 * probabilities, the temperature / top-K / top-P control panel, the
 * "set deterministic" button, and the explainer.
 * Colours come from the shared CSS variables — never hard-coded.
