Pricing Logic:

• Implement a click counter for each item.
• Trigger: When an item is clicked 5 times.
• Action: Increase the price of the clicked item by €0.20. Decrease the price of all other items in the same section by €0.05.
• Constraint: Prices must not fall below €0.00.
• Scope: Logic applies independently to each section.
• Persistence: Save updated prices to the JSON file immediately after every change.

GUI Requirements (dynamic_pricing_gui.py):

• Theme: Dark Grey background with Green accents.
• Layout: 4 distinct sections (LabelFrames) with clear boundaries.
• Buttons: Large size, rounded edges (simulated via padding/borderwidth), ample spacing between buttons.
• Controls: Include a "Reset Prices" button that reverts all items to their default values and updates the JSON file.

Dashboard Requirements (streamlit_app.py):

• Display real-time bar charts for each section.
• Auto-refresh or poll the JSON file to reflect changes immediately.
