/* ──────────────────────────────────────────────────────────────────────────
   Literary reading theme — WHITE background, refined SERIF.
   Per reader-ux.md §5: the HTML reading view is ALWAYS white; the typeface
   reflects the title's character — serif for classical/literary magazines
   (Strong Words, LRB, Granta), sans for modern titles.
   Type: Source Serif 4 (modern, screen-legible serif). Clean, contemporary,
   literary — no sepia, no fust.  Styles every class the converted HTML emits.
