+Dev-only preview tool: renders the fantasy card for two synthetic players
+(one healthy, one injured) to PNG files, without needing the actual
+LED matrix hardware or the `rgbmatrix` library.

+Run: python preview_fantasy_card.py
+Output: preview_healthy.png, preview_injured.png, preview_comparison.png
