/*
 * Driver coupon form, public side.
 *
 * Designed as a service job card: a deep petrol header stating the offer, then
 * hairline-ruled sections, with amber as the action colour. Amber rather than
 * the usual blue because this is the signal colour of the vehicle world, and
 * dark text on amber the way a road sign does it.
 *
 * Every selector starts with .ihdc- so no existing theme or plugin style is
 * changed. Nothing here targets body, html, a bare element, or a theme class.
