/* assets/css/series.css
   ------------------------------------------------------------------
   Shared stylesheet for series pages. Every rule is prefixed .series-
   and every colour resolves through three custom properties that a
   page sets on .series-page:

       --series-field   the deep / cool colour
       --series-current the connective / warm colour
       --series-mass    the hot accent

   Threshold and Magnolia Canticle currently ship near-identical
   300-line stylesheets of their own; both can migrate onto this file
   by setting their own three tokens, which would delete roughly 600
   lines of duplicated CSS. Nothing here assumes Conjunctions.
