/* Store styles. Mobile first: base rules are the phone layout, min-width queries add columns.
   Nothing of the brand is typed here. Colours and fonts are tokens from ../brand/brand.json (store.tokens, fonts),
   injected as tokens.css and fonts.css at build time:
   --ink --muted --soft --page --white --sand --rule --dark --dark_deep --on_dark --cta --cta_deep --marker --marker_tint
   --alert --alert_tint --ok --tone_a --tone_a_tint --tone_b --tone_b_tint, --font_display --font_body --font_hand.
   The chapter colours (.ch-<id>: --ch, --ch_tint, --ch_deep) are appended by the generator (pages.chapter_css).
   Look: the pages of the book. Condensed display type for headings, a different band for every section. */
