/* AI Papers Daily
   Design plan: a research terminal, not a blog.
   - Full width with small gutters. Pages read like a dashboard you check every morning.
   - Geist Pixel for headlines, numbers and labels; Geist for reading; Geist Mono for arXiv IDs.
   - Warm paper grey and near-black ink. International orange marks what matters most
     (top pick, today, progress); highlighter yellow marks what the reader chose (highlights, notes).
   - Topic colours appear only as small dots, mini charts and bars. Colour means "which topic". */
