/**
 * @file
 * @ingroup data
 * @brief Integer min and max, a packet-release helper, and the
 * single-precision angular constants.
 *
 * Address range 41d0c0-41d11f. MinShort and MaxShort have 94 call sites
 * across the game core. The constants' read-only data follows the barracks
 * menu regions and precedes the DirectDraw GUIDs, as only a unit linked
 * between those two can place it.
