   Warm, editorial, minimalist. Cream paper + a single muted sage accent.
   Type: Fraunces (display serif) / Mulish (body sans).

   HOW TO EDIT QUICKLY:
   - Colors, fonts, spacing all live in :root below — change once, applies everywhere.
   - To swap the accent (e.g. terracotta or muted blue), edit the --sage* values.
