+//! Digger — debug-only tile removal timer.
+//!
+//! This module provides the `Digger` component for demonstrating tile removal.
+//! It is NOT used in production gameplay — `ChopTree` and `MineTile` tasks
+//! will call `fell_tree` / `dig_floor` directly when executed by the task system.
+//! `Digger` lives on `Rabbit` as a debug example only.
