/**
 * OptionGrid Variation Matrix Frontend Styles

 * All styles are namespaced with the .wcvm- prefix to avoid theme conflicts.

 * Every colour, size and radius is driven by the custom properties declared in
 * the DESIGN TOKENS block below. The plugin settings screen writes the site
 * owner's values into an inline block that redeclares the same properties on
 * .wcvm-variation-matrix, so no rule below ever needs a hard coded colour.
