[Bug Fixes]
1. Fixed a bug where incorrect district location calculations caused enemy difficulty to be excessively high in some districts.
[Content Improvements]
1. Removed the "time period" element.
2. Added a "supplies" element. Constructing new buildings on the water and recruiting survivors now require consuming "supplies." Supplies can be obtained from various sources, with the most common being the daily production of "supplies" from renovated abandoned buildings.
3. Danger zones now feature a skull icon.
[Other Notes]
1. Due to the removal of the "time period" element, the beginner tutorial has been temporarily disabled and will be replaced with an updated version in the future.
