   Retina rules applied here (see LOGIN_AUDIT.md §2):
   · fovea holds only static, high-contrast content: the form. All motion
     lives in the void (periphery), and calms while a field has focus.
   · heading sits at a fixed y across every step → no re-targeting saccade.
   · state by shape, never by hue alone: filled = done, 2px = conflict,
     dashed = not yet / unverified.
   · 0 ms press feedback; no layout shift on error (messages reserve rows).
