- Chat fully migrated to the s&box platform chat: player messages, join/leave notifications, muting, and word filtering are now handled by the engine. System messages (deaths, kicks, bans) are posted into the platform chat by the host, and the secret phrase now hooks the platform chat events.
- Pressing `Enter` opened two chat boxes at once — the platform chat and the legacy in-game chat.
- The legacy chat UI, its `say` console command, and its scene object — all superseded by the platform chat. The `Chat` input action stays: the platform chat overlay opens through it.
