Accessibility
Focused practice should remain usable.
The MVP supports keyboard navigation, visible focus indicators, touch targets, reduced motion, text labels, and feedback that does not rely on color alone.
Game controls
Schulte cells, Sudoku cells, number keys, and tool controls are native buttons that can be reached by keyboard. Game state changes are announced through live text.
Visual considerations
The interface uses high-contrast text, restrained motion, and responsive layouts. Sudoku conflicts use both color and cell context.
Known limitation
Spatial grid exercises are inherently visual. Screen-reader labels describe rows, columns, values, and notes, but the current games do not provide a fully equivalent non-visual exercise.
