/* ISLE SLINGERS -- physics/damage/index.js (submodule: damage)
 * Modularization pass (behavior-neutral split of the original
 * js/core.js monolith). Installs its units into ONE shared physics scope `P`
 * that every physics submodule sees -- the same single-scope semantics the
 * monolith had. Must load before js/physics/index.js (the aggregator that
 * attaches the public ISLE_CORE API). Surface installed: damageBlock, damageEnemy.
