/*
  style.css
  ---------
  Single shared stylesheet for the Grey Ursus Consulting marketing site
  (Home, Services+Pricing, About, Contact). Loaded identically by every
  HTML page in this project. Contains: design-token custom properties
  (verbatim, per spec), a small reset, shared layout primitives (nav,
  footer, buttons, cards, forms), the hero/embers backdrop styling, and
  responsive breakpoints for tablet and phone widths. No client-side
  framework, no external font or asset requests — fonts are self-hosted
  via @font-face below.
