/* Requirements Traceability Gap Finder: a checkprint of a V-model trace sheet. A faint cool white print, graphite ink, leader
   lines from each requirement down to its children, the requirement on the left and its verification on the right. Colour
   carries status only: the checker's yellow highlighter behind a traced and verified ID, red pencil on a break (a ring, a strike
   through a changed ID, a circled finding number). Never a fill, a band or body text in red. */
