   Navegación inferior — patrón app / PWA (solo mobile)

   Antes era position:fixed con un padding-bottom "adivinado" (o incluso
   medido en JS) en el contenido para no taparlo. Eso nunca termina de
   ser confiable: con navegadores móviles la altura de viewport (100vh)
   cambia según se oculte/muestre la barra de direcciones, y cualquier
   cálculo de padding puede quedar corto según el contenido dinámico de
   cada pantalla.

   Ahora en mobile TODO el body es un flex column de altura 100dvh
   (dynamic viewport height — sigue el tamaño real visible, no el
   nominal): el nav de arriba y el de abajo son filas normales del
   flujo (flex-shrink:0, nunca position:fixed), y .tk-scroll-area en
   el medio es la única que scrollea (overflow-y:auto). No hay ningún
   padding que calcular: el bottom-nav ocupa su lugar real como
   cualquier otro elemento, así que jamás puede superponerse a nada.
