/* =============================================================================
   Strategy Library (sapience-issues #1072): the catalogue and the assessment page.

   Loaded ONLY by the two library templates, so site.css (and every live page that references it) is unchanged.
   Built from site.css's tokens: the force accents, the soft shadows, the 20px card radius, Roboto.
   Spec rules carried into the look (catalogue card spec v2, sapience-issues #1072):
     - marks are filled vs empty; the force colour only reinforces them, it is never the scale;
     - an empty mark still takes its place, so 0 reads as 0;
     - the whole card is one focusable link with a visible focus ring.
