/* undying.systems — "Ossuary" stylesheet
   Drawn from the avatar: black field, ash-grey ring, bone-white ink,
   sticker outline around the drawing, crosshatched graphite shading.
   Layout: single 68ch column; ringed avatar masthead; projects as outlined
   "stickers"; CV as a ruled ledger. Dark is the native look, light is "bone". */
