   WOS Calculator — v2 design system  ("Frost")
   ----------------------------------------------------------------------------
   Mobile-first. Every rule below targets phones by default; tablet and desktop
   are layered on with min-width queries at the bottom of each section.

   Compatibility: this file is a drop-in replacement for css/styles.css. It
   re-declares every legacy custom property name (--card-bg, --border, --text,
   --primary, --radius, --transition …) so page-specific sheets that consume
   them (territory-planner.css, the Exalted Troops block in waracademy.html)
   keep working untouched.
