 * CSB HP Armor HUD
 * Copyright (C) 2026 counter-strike-boost.com
 *
 * A clean replacement HUD that shows the player's HP, armor, money and the
 * ammo of their current weapon in a configurable corner, with colour thresholds
 * on the HP. Refreshed on a short task, toggleable per player with /hud. Useful
 * on servers that hide the default HUD.
