/* ISLE SLINGERS -- physics/constants/index.js (submodule: constants)
 * 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: WORLD, VIEW, MATERIALS, BIRD_TYPES, ENEMY_TYPES, GRAVITY, LAUNCH_POWER, MAX_PULL, MIN_PULL, AIR_DRAG, BIRD_BOUNCE, BIRD_GROUND_FRICTION, REST_SPEED, SETTLE_TIME, BIRD_MAX_AGE, ABILITY_CD, BIRD_BONUS.
