 * - ID-to-placement routing: Tracks which toast ID belongs to which placement
 * - Convenience methods: info(), success(), warning(), error() methods
 * - Promise support: promise() method that transitions loading → success/error
 * - Default duration: 6000ms, consumer-controlled (action does not override)
