# Homework: display a score on screen using pygame text.
# 1. Create a font object with pygame.font.SysFont(None, 48).
# 2. Create a score variable starting at 0.
# 3. Each frame, render a string like "Score: 0" and blit it near the top-left.
# Hint: f"Score: {score}" builds the string.
#       font.render(text, True, color) builds the surface.
#       screen.blit(surface, (x, y)) draws it.
