   auth-client — all styles
   Sections:  VARIABLES · BASE · LAYOUT · HEADER · USER MENU · LOGIN · APP · ERROR
   App-specific styling lives under the APP section at the bottom.

   Two layouts, one breakpoint:
   - mobile (default): everything up to an iPad Pro 11" in landscape (1194px).
     One column, sized to fit an iPhone 16e (390 × 844) without scrolling.
   - desktop: wider than 1194px. Only the column width changes here; add
     desktop-only rules under the same media query.

   No page is taller than the screen unless its content really needs it:
   the screen is min-height 100dvh and nothing adds height on top of it.
