/* ============================================================
   SOLENIC — PAGE SHELL
   The ground, the typeface and the grain for a normal scrolling
   document page. Linked after the tokens and base, before the
   page's own stylesheet.

   WHY THIS EXISTS
   These three things are the brand, not a page decision, yet they
   were redeclared in home.css, about/, technology.css and (briefly)
   news.css — four copies, drifting. home.css still names the legacy
   --black / --cream palette. A change to the site ground had to be
   made four times or it silently did not apply.

   Anything in here must be true of EVERY document page. Page-specific
   layout stays in the page stylesheet. The homepage carousel is a
   deliberate exception: it locks scrolling and manages its own body,
   so it does not load this file.
