NR Draw · winner card generator
===============================
Renders the WhatsApp winner card with the real winning code.
Run after the armed draw, alongside record_draw.py, so the card,
the film, and the page all carry the same result.

Usage:
  python3 make_winner_card.py --code COWYN09 --entries entries.txt
  python3 make_winner_card.py --code COWYN09 --entries entries.txt --date 22.09.2026

Output: NR_Winner_Card_<CODE>.png · 1080x1350 · ready to send.
The card is private material for the winner's WhatsApp thread only;
the public record stays code-only on the draw page.
