/* Single source of truth for Bookshelf's colour + font values, shared
   between two otherwise-separate flows:
   - the landing page (bookshelf-landing.css, scoped under .bookshelf-landing,
     rendered as standalone index.html but visually self-contained)
   - the rest of the site (stylesheets/bookshelf-material.css, mapping
     these onto Material's own --md-* variable names, applying to every
     page including the Material chrome around the landing page itself)
   Change a value here once; both flows pick it up. See
   documentation/landing-page-notes/DESIGN-SYSTEM.md's "Colour tokens" and "Fonts" sections for
   the full rationale and role of each token — this file only holds the
   raw values. The Google Fonts @import lives here too, not in
   bookshelf-landing.css — it has to be loaded once, site-wide, before anything
   references --bookshelf-ff-*, and this is the file every page already
   loads via mkdocs.yml's extra_css. */
