/* ── Books panel ────────────────────────────────────────────────
   SodBooks' stylesheet, scoped under #p-books.

   Same treatment as the School port: the original at books.home is a
   dark-first dashboard, and dropping that literally into a warm cream site
   would put a black rectangle in the middle of it and break for anyone in
   light mode. Structure kept, palette re-pointed at the shell's tokens.

   One thing that does NOT get re-pointed: the preservation ramp. It is an
   ordinal scale -- one hue, four steps, darker means more at risk -- chosen
   because it passes colour-vision separation where a red/green status pair
   fails it badly (deutan dE 4.1 for the good/critical pair). Re-hueing it to
   the shell's green would collapse the very distinction it encodes. Each
   step carries a distinct GLYPH as well, so the ramp never carries meaning
   on colour alone. */
