/* AEVORON DEEPTECH — design system v3
   Layout concept: every page is a drawing sheet. A fixed rail on the left carries the sheet number
   and a depth scale that follows the scroll; the footer closes with a title block. Dark graphite
   "field" sections alternate with cool paper "document" sections. Petrol is the working colour,
   amber is the signal (live values, cursors, alarms) and is never used as decoration. */
