/*
 * Login — the only page without the shared header/container shell, and
 * the first thing anyone sees, so it carries the design thesis whole.
 *
 * The signature here is the background, not the card: Ginnungagap, the
 * yawning void, with Niflheim's cold light bleeding in from one side and
 * Muspelheim's forge light from the other, meeting in the middle where
 * the form sits. Two radial gradients at very low opacity -- no
 * animation, no particles, no glassmorphism. The card itself stays
 * almost severe so the atmosphere reads as depth rather than decoration.
