A web application that calculates and visualizes whether objects can fit in a specific room with a sloped ceiling.

• Width: 155 cm
• Left wall height: 115 cm
• Right wall height: 255 cm
• Ceiling: Straight slope from left to right

• Real-time calculation: Enter object dimensions and see instant results
• Visual feedback: Color-coded results (green = fits, red = doesn't fit)
• Dual visualization:
  • Side view showing the sloped ceiling and object placement
  • Top view showing the floor plan and positioning
• Detailed results: Shows exact positioning, clearance, and failure reasons

1. Enter your object's width (cm) - how wide it is along the floor
2. Enter your object's height (cm) - how tall it is
3. Enter the offset (cm) - gap you want from the tall wall
4. View the results and visualizations

The application uses a precise geometric calculation that:

1. Positions the object against the tall wall with the specified offset
2. Calculates the maximum ceiling height at the object's position
3. Determines if the object fits within the sloped ceiling constraints
4. Provides detailed feedback on positioning and clearance

The core fitting algorithm handles edge cases like negative dimensions, objects extending beyond room boundaries, and precise height calculations along the sloped ceiling.
