/* Hallmark · macrostructure: Marquee Hero + F2-Stack · genre: modern-minimal.
   Theme: studied-DNA (source: whitecode.kz) translated into Lief warm-paper palette.
   Knob delta: compact ERP offers, inline RU/EN/KZ switcher, logo marquee and five-scenario demo tabs.
   Pre-emit critique: P5 H5 E5 S5 R5 V4 · nav: N1b · footer: Ft5.
   Gates: contrast, slop, honest content, tokens, responsive and mobile pass (30, 34, 40–57).
   Implementation: pointer-responsive system art, stable-height manual tabs and an accessible logo marquee, with reduced-motion and no-JS content parity. */
