/* CNT Ritual manuals — one stylesheet for the web pages and the printed PDFs.
   Layout: a booklet. A white masthead band, a title block, then a contents rail
   beside a reading column; screenshots sit in frames that may run wider than the
   text. In print the title block becomes a cover and each section starts a page.
   Colors and faces are the app's own (lib/design-tokens.ts). */
