 ## Project overview
 - Goal: Generate printable DIN A4 sheets with music cards from a Spotify playlist. Front shows a QR code plus the title and artist(s); back shows the release year and small text.
-- Current core: generate_hitster_cards.py uses Spotify’s Web API, generates QR codes and PDF pages with 3 × 3 cards per A4 (each 63 × 88 millimetres).
+- Current core: music_cards_generator.py uses Spotify's Web API, generates QR codes and PDF pages with 3 × 3 cards per A4 (each 63 × 88 millimetres).
 - Outputs:
   - Separate files mode: fronts.pdf and backs.pdf.
   - Interleaved mode: cards.pdf with alternating pages (odd fronts, even backs) via --one-pdf.
