/* =====================================================================
   ENSGAS — Premium Natural Gas Systems
   Design system & stylesheet (v1.1 — performance pass)
   ---------------------------------------------------------------------
   Rules of this stylesheet (keep it fast on low-end machines):
   • Only `transform` and `opacity` are animated continuously.
   • No `backdrop-filter` over moving content; no `filter: blur()` orbs.
   • `will-change` only on the few elements that really animate every frame.
   • Scroll reveals are owned by GSAP (js/gsap-animations.js); CSS only
     gates the initial state behind `html.js` (see §4).
   ---------------------------------------------------------------------
