/*
 * splash.css
 *
 * Purpose:
 * Visual language for the anonymous SWARMATIC gateway.
 * Shares the workbench token set — same ink, paper, accent, and
 * typography — so the transition from splash to workbench feels
 * like entering the same system, not switching products.
 *
 * The splash is not an iframe'd swarmlet. It is a full standalone
 * page and keeps its own stylesheet rather than linking swarmlet-base.
