/* GCU tools hub styles. Mirrors the look of Found-Search-Marketing/gcu-brand-tags
 * (Tailwind defaults: Geist, slate neutrals, indigo accents, slate-900 primary
 * button) as plain CSS so the hub needs no build step. Light-only, like that
 * repo. Served from /assets/, which the middleware leaves ungated so the login
 * page can load it. */
