/* ==========================================================================
  dynattenik DeStatiX-A9 — Product Site Stylesheet

  Design language: instrument-grade, dark field.
  The page sits on graphite so the product photography becomes the light
  source in the composition — the way a bench instrument reads against a
  dark panel. Elevation is carried by surface lightness, not shadow. The
  registered brand red is the only accent; signal green means "live".
  Hairline borders, tight radii, monospace for every technical identifier.
