/* ============================================================================
 * BOX BOX - prompt editor
 *
 * Loaded after style.css and built entirely from its variables. Nothing here
 * introduces a new colour, a new radius or a new type scale: this screen is
 * the reader pane in a different arrangement, not a different app.
 *
 * Every colour is a style.css token, which is also what makes this screen work
 * in both themes without a line of its own: --fail-text on red, --run-ink on
 * orange, --text-2 on a quiet panel. Type set in a status hue uses the -text
 * token, never the fill one. Two deliberate calls:
 *   1. The diff uses --done-tint/--done-ink for added lines and the fail pair
 *      for removed ones. "Jade means landed, red means gone" extends cleanly to
 *      "jade is what arrives, red is what leaves", and diff colour is one of
 *      the few conventions a reader already knows before she opens the screen.
 *      Note it is done and NOT accent: an added line is a settled fact, not a
 *      control, and the accent is only ever a control.
 *   2. The textarea is capped at a readable measure instead of filling a wide
 *      pane, for the same reason the reader is capped at --measure.
