/* Orbit public pages. Colours come from the app itself:
   apps/frontend/src/app/orbit/orbit.scss (--orbit-* tokens, dark and .light)
   and apps/frontend/src/app/(app)/auth/orbit-auth.scss (#030506 sign-in black).
   No web fonts, no scripts, nothing loaded from other sites (the CSP in _headers
   allows only this stylesheet and same-site images). No inline style attributes
   anywhere: the CSP would block them. */
