   TOPEDUPREP — Design System
   Concept: "Digital Exam Interface" — the visual language of
   the Bluebook / digital SAT screen and a graphing-calculator
   LCD, applied to an academic brand. Ink-navy field, phosphor
   mint signal color for anything "live", warm amber for dates
   and score highlights, monospace numerals for anything the
   exam clock would show.
