/* ============================================================
   IndicatorSmith — site.css
   Marketing design system for IndicatorSmith (Sept 2026):
   near-black canvas, monochrome chrome, white pill buttons, mono
   uppercase kickers, 12px cards with hairline borders and deep
   shadows, bordered split feature blocks, 1240px container.
   Every selector is prefixed `lx-` so this file can coexist with
   demo.css (the full-screen app keeps its own stylesheet).
