/* ===================================================================
   RIVOUP LTD — Design System v2 "Pinout"
   Direction: bold, dark, editorial. One sharp accent. Numbering used
   throughout is not decorative — it borrows the pin/port-numbering
   convention printed on real connector datasheets (PIN 01, PIN 02...),
   the one piece of vernacular that's actually native to a chargers-
   and-cables business.
