/* ============================================================
   UNSEEN — shared stylesheet
   Design system: "black on black".
   Two blacks (Void ground, Overdye surfaces), a cold print
   white (Optic), a faded grey (Wash), and one signal colour —
   Ultraviolet — reserved for focus states, the live dot and
   text selection. If you never reach for it, you never see it.

   Sections are grouped per component / per page so they can be
   lifted individually into Shopify theme sections later; the
   tokens in :root map 1:1 to future theme settings.
