Now let me read the existing files to understand the project structure:

Now let me build the complete 24-hour clock planner app. I'll create all the necessary components:

Now let me create a PWA manifest as required for mobile:

Let me check if there are any issues with the app:

There's a hydration mismatch due to floating point precision. Let me fix that by rounding the values:

I need to fix the hydration issue by rounding values and ensuring consistent calculation on server and client:

Now let me also add the round helper at the top of the function where we need it. Let me check the current state:

Now let me remove the duplicate declaration:

I see there's still a duplicate. Let me read the file and fix it properly:

The file looks correct now. The logs show it compiled successfully. Let me check if there are any newer errors:

The logs show it compiled successfully (✓ Compiled in 52ms) and the last request returned 200. The app should be working now. Let me verify the final state of the clock-chart to ensure it's correct:

Now there's only one round definition. The app is ready. Let me also remove the unused isDragging variable and the unused import:

Your 24-hour clock planner is now complete! Here's what I built:

Features:

• 24-hour clock visual — Time sections are displayed as arcs on a circular clock face with 00:00 at the top, 06:00 at the right, 12:00 at the bottom, and 18:00 at the left
• Interactive sections — Tap any section on the clock or legend to select it and edit in the bottom sheet panel
• Drag to move — Drag a section to move it around the clock
• Resize handles — When selected, white circular handles appear at both ends of the section — drag them to extend or shrink the time block
• Color picker — Choose from 10 vibrant preset colors for each task
• Unused time display — Any unscheduled time shows as dark gray with low opacity, with the remaining percentage displayed
• Mobile-first design — Large 44px+ touch targets, no pinch-to-zoom on inputs, bottom sheet editor for easy thumb access

How to use:

1. Tap any colored section to select and edit it
2. Drag the white handles to resize the time block
3. Drag the section itself to move it
4. Use the bottom editor to change the label, color, or exact times
5. Tap the "Add" button to create new time blocks
