/* ============================================================
   AUTH.CSS — Pantallas de autenticación (login, selección de obra)
   Migrado 1:1 desde el prototipo Onio (onio-prototipo-18.html).

   El prototipo solo define 2 estados reales para estas pantallas:
   movil apilado (default) y escritorio partido (.phone.is-desktop).
   No hay un tercer estado de "tablet" propio — por eso ac solo hay
   UN breakpoint, no tres. Una tablet en vertical (~768px) recibe el
   layout de telefono (funciona bien ahi, ya que es basicamente una
   columna centrada); una tablet en horizontal o un notebook chico
   (>=1024px) recibe el layout de escritorio.

   1024px se eligio porque:
   - Es el breakpoint "lg" que usan Tailwind y la mayoria de sistemas
     de diseño modernos para el salto a layout de escritorio.
   - Es el ancho horizontal exacto de un iPad en landscape — o sea,
     el dispositivo tablet mas comun cae justo en el lado "desktop"
     cuando esta acostado, y en el lado "telefono" cuando esta de pie,
     que es el comportamiento esperable.
   - El layout partido (hero + formulario) necesita al menos ~900px
     para no verse apretado; 1024px da margen.

   Mobile-first:
   - Base (sin @media)         = telefono y tablet vertical
   - @media (min-width:1024px) = escritorio y tablet horizontal
