/* =====================================================================
   ĮKROVIMO EKRANAS v2 (v889, Domantas 2026-09-24: „loading gražesnis — dabar kaip žaidime, noriu gražaus, kieto“)
   Ramus, „inžinerinis“: tamsus gilus fonas su perspektyvos tinkleliu, izometrinė katilinė, kurios vamzdžiai
   nusipiešia linija ir per juos teka šiluma; Protis 3D ženklas ir plona eigos juosta. Jokių besisukančių žiedų.
   Klasė .ls-v2 — kad nugalėtų senas taisykles (menu-ui.css html.ui-ld, skin-clay.css).
