Mistake: Using letters or numbers instead of proper geometric shapes for UI elements
Fix: Use the correct Unicode geometric shape (■ square, ● circle, ◆ diamond) rather than approximating with letters like O, 0, or □.
⚠️
Mistake: Confusing similar geometric shapes that look alike at small sizes
Fix: At small sizes, ■ (black square) and ● (black circle) may look similar. Test at actual rendering size and ensure the shape conveys the intended meaning in context.
