/* Sign-in family (login / register / forgot / reset) — Oct 2026 redesign from the "Birewer Sign-in
   Redesign" canvas. Rendered bare (MainLayout.IsBare), so nothing from the Cuba shell or the paper
   book is on the page. Three layouts from one DOM (AuthFrame.razor):
     ≥1000px  desktop: two-panel card, brand panel at inline-start, form panel at inline-end
     600–999  iPad / narrow: one stacked card (brand band above the form), language pills in the band
     <600     phone app: edge-to-edge brand band, the form sheet slides over it (rounded top)
   Colours are the theme.css tokens; the few literals here are tints of them. */
