/*
 * Citoviso UI — the central design core ("dizájn-mag").
 * ADR-0021 ①: ONE source of truth for ALL first-party Citoviso surfaces
 * (public homepage, login, internal console, tenant-admin chrome).
 *
 * SCOPE BOUNDARY: this is the CONTROL-PLANE product brand — ONE stable Citoviso
 * identity. It is NOT the engine's per-skin `--cit-*` token contract, which themes
 * GENERATED tenant sites (data plane, variable per skin). Namespace is `--citui-*`
 * on purpose, to never collide with the engine tokens.
 *
 * Design language: navy/cyan brand, Space Grotesk (display) + Inter (text),
 * dark-gradient heroes, glassy surfaces. Icons are inline SVG (no emoji).
