Flashcard Font Size Adjustment

Users should be able to adjust the font size of text on flashcards to improve readability and cater to individual preferences. This would enhance the user experience, especially for those with visual impairments or who prefer larger text. Technical Details: Implement a setting within the flashcard customization options that allows users to select from a range of predefined font sizes or a slider for granular control. This setting should persist across sessions and apply to all flashcards.
