• Kit delivery – optional full inventory replace on claim, optional auto-equip armor when slots are empty, title/sound on claim

• Vouchers – redeemable codes (/kits redeem) and right-click item vouchers (one-time claim or permanent unlock); optional dupe-security console command
• First join & respawn – configurable automatic kit names in config
• Logging & stats – claim log command, per-kit claim counters and last claim info (cached)
• Integrations – {player} / {uuid} and PlaceholderAPI in kit commands; optional Discord webhook for admin actions; optional API webhooks on claim
• Data safety – export single kits to YAML, full folder backup/restore with pre-restore snapshot
