/* ============================================
   nation-seat-calc.css - Scottish / Welsh seat calculators
   --------------------------------------------
   Page-specific layer for scottish-seat-calculator.html and
   welsh-seat-calculator.html. Everything structural comes from
   css/pc-components.css; this file only adds what those two pages need
   and nothing else on the site has yet. Tokens only, never raw hexes.

   Graduation rule: if a second page needs one of these, move it into
   pc-components.css and add a specimen to /design-system.html.
