/*
 * CSB Welcome MOTD
 * Copyright (C) 2026 counter-strike-boost.com
 *
 * Shows a welcome MOTD (a local HTML file or a URL) once per player per map,
 * after a short delay, plus a personalised coloured chat greeting that includes
 * the player's name, score and country (resolved with GeoIP). A cvar makes the
 * MOTD show only the first time a SteamID is ever seen, tracked with an nVault
 * flag so it survives map changes and restarts.
