/* Signal & Ink (MemberBox template) — design system.
   Solo-writer paid-newsletter theme: near-black ink + a single crimson
   accent + a warm cream "paper" background, with serif headlines (editorial
   masthead feel) over a plain system-sans body/UI — deliberately distinct
   from the all-sans navy/gold CourseBox, plum/gold SubBoxBiz, navy/amber
   PetCareBox, teal/coral MoveInServicesBox, dusty-blue/gold SeniorConciergeBox,
   and forest-green LawnCareBox palettes sitting next to it in the same
   account. Divider motif is a newspaper-style masthead double-rule instead
   of a dashed line/ribbon/paw/stripe. */
