/* ============================================================
   SIGN IN / SIGN UP — the front door (ui/LoginScreen.js) and the
   parts it shares with Settings › Account (ui/AuthKit.js).
   Also: the What's New log (game/Changelog.js, .cl-*) and the guided
   tour card (ui/WelcomeTour.js, .wt-*) — the rest of the first-run path.
   ============================================================
   Two compositions over one set of controls:
     .auth-desk   desktop split screen: the STAGE (the brand and one
                  machine under a spotlight) on the left, the DOCK
                  (full-height form panel) on the right.
     .auth-phone  the compact layout: a tilted wall of machine emblems
                  behind the crest, and a bottom sheet with every control
                  in thumb reach. Tablets get the sheet as a floating card.
     .auth-panel  the flow in one column, inside the Settings modal.

   Follows the house contract (styles-premium.css):
   - keyframes animate transform / opacity only (plus the stroke draw on
     the success seal); entrances use `backwards` fill;
   - hover rules sit inside @media (hover: hover);
   - every keyframes class is silenced under .reduced-motion, and the
     ambient loops also under .performance-mode (GUARDS, at the bottom).
   - At rest the whole screen runs ONE ambient animation: the desktop
     spotlight's living emblem (styles-emblems.css). The phone's reel
     wall spins once on arrival (Web Animations, in LoginScreen.js) and
     then stands still.

   Rules are scoped under .auth-root where they touch buttons or inputs:
   the Tailwind CDN injects its preflight AFTER this sheet, so an unscoped
   single-class rule could lose to it on source order.
