/*
 * Shared RitchAI navbar + live ticker.
 *
 * This file is injected into EVERY page on the site, including the pages built
 * by the Inside Trader (Flask) and Macro (Vite) repos. Those pages carry their
 * own stylesheets and their own :root custom properties, so nothing here may
 * depend on the host page: every selector is prefixed `.rai-` and every colour
 * is resolved from `--rai-*` variables declared on `.rai-bar` itself.
 *
 * Served from the site root, so `/ritchai-nav.css` resolves from any depth
 * (e.g. /portfolio-tracker/overlap/365/all/).
