 * CSB Team Gravity
 * Copyright (C) 2026 counter-strike-boost.com
 *
 * Applies a per-team gravity multiplier with set_user_gravity on every spawn,
 * used by mods like Furien or Hide'n'Seek where one side should jump higher or
 * fall slower than the other. The values are cvars (1.0 = normal), and when the
 * plugin is disabled every player's gravity is reset to normal.
