/* Login stage — dedicated composition (does not replace app chrome).
   Design basis:
   - 8pt rhythm + optical grouping (Gestalt proximity)
   - One vertical column (Nielsen: credentials never side-by-side)
   - Fitts: ≥44px targets, full-width primary
   - Brand as hero of the first viewport; form as single interaction group
   - Liquid Glass as material on the card only
