/* Koh Chang Taxi — a ticket, not a brochure.
 *
 * The first version of this file was the Khao Yai stylesheet with the colours
 * and fonts swapped: 84% of the selectors were identical, the same photo hero,
 * the same section rhythm, the same fare cards and accordion. That is a template
 * skinned twice, which is the thing this whole job exists to stop.
 *
 * So this one starts from what the site is for. Nobody arrives here wanting a
 * landing page; they arrive wanting to know whether a flight landing at 15:00
 * still makes a boat. The page is therefore a planner first and a brochure
 * second, and it is dressed as the object the journey actually produces — a
 * cash ferry ticket bought at a window: perforated stubs, dashed rules, stamped
 * labels, everything in a typewriter face because that is what a ticket is set in.
 *
 * There is no photo hero. The photograph appears once, later, as a full-bleed
 * band between sections, where it does a different job.
