/* ChatAI Engine -- website agent chat widget.
 *
 * Same dark/green identity as the rest of the marketing site (reuses the
 * --mk-* tokens already declared on :root in marketing-original.css,
 * loaded on every page this runs on -- no separate palette invented for
 * it). Real classes only: this file is a linked stylesheet, not JS-
 * injected, specifically because this widget runs on chataiengine.com
 * itself and is bound by this app's own CSP (style-src 'self', no
 * unsafe-inline) -- unlike the tenant webchat widget.js, which runs on a
 * stranger's page and is exempt from it.
