⚠️ Note: This mod and its changelog are AI-Assisted.

🆕 New Features & Mechanics

Medical Monitor:
- A new diagnostic item that displays your exact disease progression percentage directly in chat upon use.
- Cost & Cooldown: Consumes 0.5 hearts ($\frac{1}{2}$ heart) per check and has a 10-second cooldown.
- Initial Drop Mechanic: When starting a fresh world, once you step 5 blocks away from your initial spawn point, the monitor automatically drops from your inventory, dealing 1.5 hearts of damage.
Starter Perks for New Players:
- Starter Chest: A chest now spawns directly under your feet upon joining a new world containing 3 free Pills.
- Guaranteed Carrot Drop: Your first killed Zombie is guaranteed to drop a carrot (if you don't already have one in your inventory) to ease early-game progression.
World Generation Toggle:
- Added a dedicated toggle button in the Create World menu to easily enable or disable mod mechanics for specific saves.
Pill Cooldown:
- Standard pills now have a 3-second cooldown to prevent accidental rapid consumption.
Quality of Life (QoL):
- Created a dedicated Creative Tab containing all mod items.
- Added clear, informative hover tooltips for mod items in the inventory.

Stage thresholds have been pushed further back to give players significantly more time to gather remedies and prepare:

Standard Pill: Now reduces disease progression timer by 20 minutes (up from 15 minutes).

To offset the longer survival timers and enhanced pill potency, gathering raw ingredients now requires slightly more effort:

Medicinal Powder (from Iron Ore): Drop chance reduced from 50% ➔ 20%.
Neutralizer (from Stone):
- Single drop chance reduced from 5% ➔ 2%.
- Double drop chance reduced from 2% ➔ 0.5%.

Cleaned up deprecated registration code and internal technical debt for improved performance and stability. No player-facing content was removed.
