/* ==========================================================================
   Softineo: plany interaktywne na wspólnym silniku STCS.Demo (js/stcs-core.js):
   symulacja zakładu, automatyzacja ważenia, kontrola tankowania.
   Ładowanie: css/softineo.css → css/demo.css → (opcjonalnie) css/<strona>.css.

   Arkusz (pierwszy ekran)
     section.sheet.demo-sheet > .refs… + .sheet-body.demo-body
       .demo-main   > .sf-map-card.sf-sim (plan + .sf-map-bar) + .demo-cards (karty scenariuszy)
                      [+ .demo-under: karty obok historii, wariant .demo-body--wide]
       .tb.demo-side > .tb-head (h1, .tb-lead, .tb-actions) [+ aside.sf-panel] + dl.stamp
   Silnik tworzy: .sf-cards-group, .sf-cards > button.sf-card(.is-warn/.is-active),
     .sf-log li(.info/.ok/.deny/.warn/.op/.muted/.empty) > .t + .m (+ .sf-doc), pingi i osoby.
   Rysunek (SVG .sf-map): klasy m-*; .sf-dev.is-hot = bieżące urządzenie (żółta obwódka,
     filtr #f-hot w <defs> planu), .sf-dev.is-dim = urządzenie spoza scenariusza.
     Trasy (.m-route/.m-walk) są .sf-dev z data-mod: widać tylko trasę bieżącego scenariusza.
   Kolory ustawiane przez skrypty (lampy, tablice LED, ramki odczytu) NIE mają fill/stroke w CSS.
