/* Cenvarel public site — stylesheet
   Direction: "Dispatch". Paper ground, ink, one blue for actions and links, one signal colour used
   once per page (the missed call), kraft for the footer and quoted messages. Humanist sans for
   headings and controls, a text serif for reading. No cards, badges, kickers, gradients or shadows.
   System fonts only; no inline styles or scripts (strict CSP). Light theme only.

   Order: tokens → base → layout → header/footer → components → page sections → utilities → print. */
