/* PB Usage & Engagement (CLO-260) — module-scoped styles.
 * Categorical palette validated (dataviz six-checks) on BOTH surfaces:
 *   dark #08101F and light #ffffff. Fixed hue order; color follows the
 *   module entity. Light-mode contrast WARN on s3/s4/s5 is relieved by
 *   direct value labels + data-table toggles (never color-alone).
 * Uses kit tokens (--fg, --fg-mute, --card-ink, --line-2, --accent). */
