/* AxiomGate public layer.
 *
 * site.css carries years of accreted page styles. This file sits on top of it
 * and does three things: it moves the public pages onto the same tokens as
 * Admin and Portal (src/ui/static/axiomgate-ui.css), it defines the sections of
 * the redesigned homepage, and it replaces the four Tailwind utilities the
 * pages still used, so the 451 KB Tailwind runtime no longer has to load.
 * Loaded after site.css; anything here wins by order, not by !important.
