 * theme.css — the shared design system for the owner dashboard and the

 * lives in dashboard.css / booking.css, which both load this first.
 *
 * DIRECTION — "yellow plate".
 * Every commercial vehicle in India carries a yellow number plate with black
 * lettering. That is the single most recognisable mark of this business, so
 * it is the accent: warm plate yellow on plate black, used sparingly, against
 * a warm paper surface that reads like the duty slip a driver actually fills
 * in. Registration numbers, booking IDs, fares and distances are set in a
 * monospace face because they are register values, not prose — that
 * distinction is real and worth showing.
