/**
 * Shared status chip tints + dashboard task-priority chips.

 * **Rendering primitive:** `ListHubStatusBadge` (`components/list-hub-status-badge.tsx`)
 * for any status chip on a list hub. Map your domain statuses onto
 * `LIST_HUB_STATUS_TINT_*` below before introducing new colors.
 *
 * **Reference consumers:** `columns-showcase.tsx` (catalog),
 * `library-board-view.tsx` (board card status row), `task-priority-badge.tsx`
 * (dashboard task chips).
 *
 * **Icon-on-tinted-disc** (insights / activity rows): `TintedIconDisc` + `--icon-disc-*`
 * in `app/globals.css`.
 *
 * Labels stay **sentence / title case** (e.g. "Due soon", "Under review"). Do **not**
 * add `uppercase`.
