I'll implement a player health tracking system with healing mechanics at the Expedition Base and through consumable items.

I've implemented a comprehensive player health tracking system with healing mechanics. Here's what I've added:

1. Player Health Tracking:

   • Added maxHealth and currentHealth properties to the PlayerStats interface
   • Added functions to handle taking damage and healing
   • Health increases by 10 points with each level up
   • Players are fully healed when they level up

2. Healing at Expedition Base:

   • Added a healing option at the Expedition Base (only visible on the map page)
   • The healing cost is proportional to missing health (1 gold per 2 missing health points, minimum 5 gold)
   • Players can see their current health status with a color-coded health bar
   • The healing UI shows the cost and allows players to heal if they have enough gold

3. Medical Items for Healing:

   • Updated medical items to include healing properties:

     • First Aid Kit: Heals 50 health (2 uses)
     • Universal Antidote: Fully heals (1 use)
     • Expedition Rations: Heals 10 health (15 uses)
   • Players can use these items during expeditions to restore health
   • The inventory display shows healing properties for medical items

4. Combat Integration:

   • Updated the combat system to affect player health
   • Monster damage is applied to the player's health
   • Players can die in combat if their health reaches zero
   • Higher exploration rounds increase monster damage

5. UI Improvements:

   • Added a health bar to the player stats component
   • Color-coded health bar (green > 60%, yellow > 30%, red ≤ 30%)
   • Added healing notifications in the expedition log
   • Updated the inventory display to show healing properties

This system adds a new layer of strategy to the game, as players must now manage their health alongside other resources. They can choose to spend gold for healing at the base or use valuable medical supplies during expeditions, creating interesting trade-offs.

I'll fix the blank expedition page by providing a complete update that properly integrates the health system.

I've fixed the expedition page by providing a complete implementation that properly integrates the health system. The page now includes:

1. A health status section showing the player's current health with a color-coded health bar
2. A medical supplies section that appears during expeditions when the player is injured
3. The ability to use medical items to restore health during expeditions
4. Visual indicators in the expedition log for healing events (green text)
5. Proper integration with the player context for health management

The page should now load correctly and allow players to manage their health during expeditions. Medical items can be used directly from the expedition page, and healing notifications will appear in the expedition log.
