/* MangalBhawan — commerce UI
 *
 * An extension of the Kundli & Panchang design system, not a second one. The
 * paper, ink, hairline rules, tabular figures and eyebrow labels are that
 * system's; what is added here is only what selling needs and an almanac
 * does not have.
 *
 * The system's rule is that each colour carries one meaning, so:
 *   crimson  stays nav-only. A primary button is INK, matching the rule that
 *            a selected control is ink-dark rather than crimson.
 *   green    means settled. On a panchang it means auspicious. The two never
 *            appear on the same page, which is the only reason reusing it is
 *            honest rather than confusing.
 *   neutral  means awaiting — an amount due, a quote not yet answered.
 * No new hue was invented. The one memorable element on these pages is
 * structural: the spend rail, which is the panchang rail carried into money.
