/* =============================================================================
   ZeroSettle v4 — "Calm infrastructure for ambitious revenue teams"
   Evolution layer over the zs26 system (css/redesign.css). Loaded LAST so it
   wins on source order. Scoped under .zs26 to match existing specificity.

   Adds: v4 tokens, bigger grotesk type, ink-primary CTAs + green accents,
   refined floating-glass nav, environmental-image system, ordered-dither
   surfaces (paired with js/dither.js), scroll reveals + parallax (js/motion.js),
   floating scroll cue, Autopilot live matrix, 3x2 dither-hover outcome grid,
   and intentional ultra-wide (>1920px) behavior. Full light + dark support.
   Honors prefers-reduced-motion throughout.
