@Head Moderator, leads the mod team, can promote/demote @Moderator.
@Moderator, handles day-to-day moderation, mutes, kicks, ban appeals.
@Helper, answers questions in #help, escalates issues to @Moderator.
@Trial Mod, applying for @Moderator; can mute but not kick or ban.
@Verified, passed verification; can post in main channels.
@Member, default on join; limited to #welcome + #rules.
