   PHONE LAYOUT v3 - everything fits on ONE screen, no page scroll.
   - Container is pinned to the real visible screen (position: fixed),
     so the browser toolbar / 100vh bug can no longer cause scrolling.
   - Black panel height is a variable; the form takes the rest.
   - Sizes scale with screen height so small phones still show it all.
   - If the screen is very short (keyboard open / landscape), the panel
     shrinks to a slim bar and the form area itself can scroll as a
     last resort, so nothing is ever cut off.
