/* Grader — grading bench on top of the Modernist design system.
   ../modernist.css owns color, font, radius and shadow tokens; this file
   lays out the tool: masthead, the stage (the image being graded) and a
   right-hand panel with the frame's named colors, the grade shelf and the
   notes of the selected grade. The graded image keeps its own colors —
   the chrome stays ink on ground. */
