   Ground black, ink warm white, one amber accent on the single control (Go).
   Two faces: Big Shoulders Display for the name and headings, Instrument Sans for everything else.
   Five sizes. Surfaces step in tone; nothing is drawn with a line. Square corners throughout.
   Layout: a full-screen cue stack, then full-bleed panels, then narrow flowing sections on one grid. */
