/* Trace powered by BATech · sign-in page (public: app.css is session-gated, so this file carries its own tokens).
   Split layout: the always-dark art panel ("a trace", TR-LOGIN) and the form column. Under 1024 px the art
   becomes a 3:1 band; under 600 px it is omitted, so the form and the full disclaimer come first. */
