// A token-driven Alert primitive replacing the family's ad-hoc role="alert" /
// role="status" notice divs. Each variant is a soft-filled, colored-border block
// that recolors correctly on every base (light, dark) via the semantic
// tokens. Callers keep control of the a11y role (default "alert"; pass
// role="status" for non-urgent notices) so existing e2e querying by role stays
// green. An optional leading icon is supported via the grid layout below.
