# Prefilled Loadout

A hotbar that boots from a saved loadout: the first three `slots` arrive already equipped with Fireball, Heal, and Blink (each a `{ id, spellId, icon, name }` entry), while the constructor pads the remaining positions out to `maxSlots` so the player can still drag in Meteor or Barrier from the available tray or click any filled slot to clear it.
