/* Constian, holding page.
 *
 * Deliberately one hand-written stylesheet and no build step. This site exists
 * to be replaced: the real one is the inherited Next.js app in web/, refactored
 * once there is a product to describe. Until then the whole point is that every
 * byte served is auditable at a glance, because the home page must not reveal
 * anything about what is being built.
 *
 * Brand values are the app's, from app/lib/theme/tokens.dart. Kept in sync by
 * hand rather than by a pipeline, because there are four of them.
