/* gym — pipeline console
 *
 * The look is a lab instrument readout rather than a dashboard: monospace is the
 * display face, because every primary datum on every page is an identifier, a
 * score, a token count or a cost. Prose gets the system UI face and stays out of
 * the way.
 *
 * Two accents, and they mean something rather than decorate: teal is clinical,
 * magenta is communication. Those are the pipeline's two independent score axes,
 * which the stage-1 rubric says are meant to disagree, so anywhere the two appear
 * together they keep these colours.
 *
 * No web fonts and no external anything: this runs on localhost, often on a
 * machine that is offline, and a stylesheet that reaches for a CDN is a console
 * that renders wrong exactly when you need it.
