Your Flavor 4.0.1

Fixed

• Rolls and card messages now use the 4.0 roll/card styling surfaces by default instead of being blocked by the legacy simple-chat-only policy.
• Existing 4.0.0 worlds with the accidental simple-chat-only default are migrated once to the supported roll/card policy.
• Shadowdark cards are treated as supported generic cards, and roll surfaces inside supported cards can now receive the configured roll styling.
