Literary Fiction Book Cover

Typography:
- Title: Large, commanding, distinctive letterform
- Author name: Smaller, clean, professional
- Publisher imprint: Small, bottom spine area

Composition: Strong visual hierarchy, title readable at thumbnail size, spine design included ([SPINE_WIDTH]mm)
Back cover: Color-matched, blurb placeholder, barcode area

[Highlighted] words are yours to fill in.
