• Built as a single HTTP-triggered Val
• Uses browser's built-in SpeechSynthesis API for text-to-speech
• Styled with TailwindCSS
• Includes dark mode support based on system preferences
• Fully client-side with no backend dependencies

The application helps you practice various French number patterns:

• Basic numbers (1-16)
• Teen numbers (17-19)
• Tens (20, 30, 40, etc.)
• Compound numbers (21, 22, etc.)
• Special cases (70s, 80s, 90s)

Numbers appear in various contexts within the train announcements:

• Train numbers (usually 4-5 digits)
• Platform/track numbers (1-25)
• Time (hours and minutes)
• Delays (in minutes)
• Car/wagon numbers

This provides realistic practice for understanding numbers as they would be used in actual French train stations.
