Reaction roles
The three modes
Standard vs Unique vs Verify.
Standard
Members can pick multiple roles. Reacting adds the role; unreacting removes it. Use for opt-in tags like notification preferences.
Unique
Members can pick exactly one role from the panel. Reacting to a new option removes the previous one. Use for pronouns, country, age range.
Verify
Reactions only ADD roles, never remove. Use for one-time gating panels (e.g. "react to confirm you read the rules") where you do not want members to lose access by accident.
