// Specs Codex — spell_unlock_costs.json
// Optional PER-SPELL XP cost overrides for Codex tier unlocks (+ button).
// Same units as school_unlock_costs.json: levels-worth of XP from 0.
// Omit a spell (or use {}) to fall back to school costs / default (20 + 10 x tier).
// Priority: this file -> school_unlock_costs.json -> default. Focus = extra 25% off.
// Edit on the SERVER, restart, then rejoin. Spell ids are in known_spells.json.
//
// EXAMPLE (commented — copy this shape into the JSON object below):
//   "irons_spellbooks:fireball": {
//     "1": 15,
//     "2": 25,
//     "3": 40
