/*
 * Styles for the surfaces on the application layout: the deliberately empty
 * branded root landing and the admin login form. Linked explicitly by
 * layouts/application.html.erb — never via an asset glob (U3 contract), so
 * nothing here leaks into the widget/chat surfaces, and widget.css never
 * leaks in here. Brand tokens (--lc-*) come from tokens.css, linked before
 * this sheet. No inline styles anywhere — CSP lands in U6.
