Namespaces
namespace	systems
	Client-only input sampling system — split into two halves so mouse look can run every iterate() (smooth camera at any FPS) while movement keys run once per physics tick group (server-consistent).

Functions
bool	systems::overlapsAABB (glm::vec3 aPos, glm::vec3 aHalf, glm::vec3 bPos, glm::vec3 bHalf)
	Test whether two axis-aligned bounding boxes overlap.
glm::vec3	systems::viewForward (float yaw, float pitch)
	Forward direction implied by a player's yaw + pitch.
bool	systems::isPlayerLookingAtPickup (glm::vec3 eye, glm::vec3 viewFwd, glm::vec3 pickupPos)
	True if the eye is within range of pickupPos and viewFwd points within the look cone.

Variables
constexpr float	systems::k_pickupRange = 140.0f
	Maximum distance (units) at which a player can press F to pick up.
const glm::vec3	systems::k_weaponPickupHalfExtents {32.0f, 32.0f, 32.0f}
	Shared pickup collision half-extents for weapon spawners and dropped weapons.
constexpr float	systems::k_pickupMaxAngleDeg = 12.0f
	Half-angle (degrees) of the look cone for press-F pickup.
const float	systems::k_pickupMinDot = std::cos(glm::radians(k_pickupMaxAngleDeg))
	Pre-computed cosine of the look cone half-angle.

Detailed Description

Shared geometry helpers for weapon-pickup proximity tests.

Used by WeaponSpawnerSystem, DroppedWeaponSystem, and the client-side HUD pickup-prompt sweep so the "is the player close enough and looking at the pickup" rule lives in one place.
