//! The `GroundPool` entity — a stationary, behavior-carrying field (acid, slow, ...). A pool
//! is NOT an enum of kinds; it's a stationary projectile carrying the same composable behavior
//! list, so "acid pool" and "slow field" are configured *instances*. The `PoolBehavior` trait
//! and dispatch live in `crate::behavior::pool`; concrete ticks live in `crate::pools`.
