🔐 SparkLogin

Modern graphical authentication for Paper servers.
No chat commands. No bloat. Just a clean dialog UI that gets players in fast and safe.

• Dialog UI — graphical login & register screens, no typing commands in chat
• Smart version routing — pre-join dialog on 1.21.11+, post-join dialog on 1.21.4–1.21.10
• Full lockdown — movement, chat, commands, inventory all blocked until authenticated
• Session auto-login — returning players skip the dialog if their session is still valid
• BCrypt security — configurable cost factor, brute-force delay, max attempt kicks
• AuthMe migration — one command imports all accounts, supports SHA256 & BCrypt hashes
