/*
 * Sample and quote requests, and the tracking page — B3.
 *
 * Without scripting a request form is a section of the fabric page, shown
 * only while the address points at it (:target). With requests.js it lives in
 * a modal <dialog>: a sheet from the inline END on a wide screen, the whole
 * screen on a phone. Errors are said in words and marked with a rule and a
 * weight, never by colour alone (the palette has no red that reads at body
 * size on paper — tokens.css).
