* ActionButtons Component
*
* Provides two primary combat action buttons:
* - Attack Button (⚡): Primary combat action, 80x80px
* - Block Button (🛡️): Defensive action, 70x70px
*
* Features:
* - Touch-optimized with minimum 44x44px targets
* - Attack button: 80x80px for primary action
* - Block button: 70x70px for secondary action
* - Visual feedback on press
* - Haptic feedback for tactile response
* - Korean cyberpunk theming
* - Hold-to-block support
*
* Usage in Combat:
* - Attack: Executes current stance technique
* - Block: Activates defensive guard (hold for sustained block)
*
* @example
* ```tsx
* <ActionButtons
* onAttack={() => executeTechnique()}
* onBlock={(eventType) => {
* if (eventType === 'start') {
* activateBlock();
* } else {
* deactivateBlock();
