     main.auth.au            two columns ≥ 981px: brand side | form card
       aside.au__brand       chip, Sora headline (2nd line gradient), one
                             honest line, and the stage: one real menu
                             render in a .sh-device with the floating
                             crystal (.sh-gem) beside it
       section.au__side      .au__card (state ring + shake) › .auth__box:
                             .au-discord button, .au-consent line, the
                             dev-only .au-dev row
     ≤ 980px                 one column; the brand block shrinks to crystal
                             + headline + line above the form, no device

   States (set by auth-fx.js from what the page module already does)
     .au__card.is-busy / .is-err / .is-ok / .is-leaving
     .au-discord.is-off (sign-in not configured)
     .au.is-off  (brand side off screen: its loops pause)

   Motion: transform/opacity only; the drop-shadow sits on the still
   crystal image, the wrapper bobs; nothing here is full screen.
