/* Harbour City Motors — navy #002850 / bright blue #057BD2.
 * Light theme: pale blue-grey page, white cards, navy buttons/nav,
 * bright-blue prices/highlights. Dark theme: deep-navy page/cards,
 * brighter blue buttons, sky-blue highlights. The logo is dark navy on
 * white, so it always sits on a white panel in the header, in both modes. */
