Now I'll build a clean, refreshing water intake tracker with a calming blue theme. I'll update the globals.css with a fresh water-inspired color palette and create the components.

Now let me create the water tracker component and the main page:

Your water intake tracker is ready! It features a clean, calming blue-themed design with:

• Visual progress ring showing your daily hydration percentage
• Glass counter bars that fill up as you log each glass
• Simple controls - tap the plus button to add a glass, minus to remove, and reset to start over
• Daily goal tracking - targets 8 glasses (2L) per day
• Persistence - your progress saves locally and resets each day
• Mobile-optimized - 44px+ touch targets and a centered, card-based layout

The app tracks your water intake in 250ml glasses and provides encouraging feedback as you work toward your daily goal.
