/* Headwaters Waterworks
 *
 * Warm, light, and quiet, so the photographs carry the page. The palette
 * is taken from the job site: paper-white and dust for the page, asphalt
 * for type, work-zone orange (black on orange, like a job-site sign) for
 * the emergency line only, and safety amber for the things you press.
 * Headings are Barlow Semi Condensed, a face drawn from highway signage.
 * Photos sit to one side of each section and dissolve into the page
 * before they reach the text.
