/* ==========================================================================
   BookBuzz design system

   Set like the front matter of a well-made book: warm paper ground, ink-black
   text, hairline rules instead of drop-shadowed cards, one measured column for
   prose.

   The recurring motif is the second-hand bookseller's endpaper annotation —
   the price pencilled inside the front cover. Offers are ruled rows: retailer
   in sans, condition in mono small caps, price right-aligned in graphite mono,
   the best one marked with an oxblood rule rather than a coloured badge. That
   motif belongs to the used-book market, which is the part of this product no
   competitor has.

   Loaded on every page, independent of the Tailwind build.
