/* TPS Repair site: visual system.
 *
 * This file is normative. It is the design, not a description of it: an agent
 * building a new page changes markup and reuses these classes, and does not
 * invent sizes, colours, or spacing. See README.md beside this file for what
 * each component is for and for the rules CSS cannot hold.
 *
 * Direction: "documentation shell", with a sticky in-page contents rail beside a
 * text column held to the prose measure. Chosen 2026-08-15.
 *
 * No web fonts and no build step. The consent controller and the checkout form
 * controller are the only site JavaScript, and every page is complete without
 * either; Google Analytics is loaded only after affirmative consent on the
 * three allowlisted information routes.
 * On the deployed site this file is served as /assets/site.css.
