Here's your Greek Letters trainer! Here's what it includes:

• Three modes — lowercase only, uppercase only, or both mixed together
• Drawing canvas — trace the letter with your mouse or finger (touch-friendly)
• Reference display — shows the letter and its romanised name
• Clear button — wipe the canvas and try the stroke again
• Next button — moves to the next random letter and tracks your progress
• Letters are shuffled randomly so practice stays fresh

Let me know if you'd like any additions — like stroke order hints, a timed quiz, or spoken pronunciation!
