An enhanced Tic-Tac-Toe game built with .NET MAUI, featuring animated interactions, accessibility support, AI opponent mode, and a unique gameplay twist:

When a player places a third symbol (X or O) without creating a winning line,
the oldest placed symbol begins to "breathe" to visually warn the player it will be removed on the next move.

This turns classic Tic-Tac-Toe into a more strategic and dynamic experience.

If a player forms a line of three in a row, that player immediately wins.

If placing the 3rd symbol does not result in a win:

• The oldest placed symbol starts to breathe (soft scale animation)
• On the next move, that oldest symbol is removed
• The board always contains at most 3 symbols per player

This keeps the board in constant motion and prevents stalemates.

The app is fully accessible:

• All cells have SemanticProperties.Description
• Animations do not cause flashing or flickering
• High-contrast theme supported
• Colors validated against WCAG contrast guidelines
