Function item_experience

pub fn item_experience(level: f64, quality: f64) -> i64

Character XP paid by selling one item, from the item’s snapshot character level and its quality multiplier quality (the rarity axis M).

Level and quality are the ONLY inputs: two items of the same level and quality pay the same XP regardless of stat roll, optional stats or power_bonus. No per-sale cap — a lucky sale may carry the player through several levels and the whole overflow is kept.

Env overrides (sim sweep): OVERLORD_BAL_ITEM_XP_COEF, OVERLORD_BAL_ITEM_XP_EXP, OVERLORD_BAL_ITEM_XP_LATE_EXP.
