#1 Castle flags now show the owner guild's logo: resolve owner name -> guild logo (cached), broadcast C1 B9 02 (32-byte mark) to players on the castle map every 15s. #3 War atmosphere: spawn catapult NPCs 221/222 at siege start (client renders them as siege weapons); the 0xB2/0x17 start flag already flips the map to warzone mode. All raw S6 packets, no client changes. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
