/* The product site: the front door (the landing, pricing, the docs, the legal pages). Every colour and
   face is a role of the Volter brand (company decision 0018): the build fetches the brand's tokens into
   brand/tokens.css, which every page links before this sheet, and the names below are this sheet's
   aliases for those roles; the pre-commit hook refuses a literal colour here. The roles carry both
   themes (light-dark()), so the page follows the reader's light or dark setting. */
