/* Varianta — Design DNA
   Direction : dark "data lab" / applied-math console — dark ground, magenta+violet data accents, scatter/distribution visual language (NOT a green-on-black terminal)
   Layout    : off-grid data-lab; nav → asymmetric scatter hero → numbered learn-index → sample-lesson 62/38 split with SVG curve → hanging-label two-column tools → instructor bleed split → pricing 2 plates → FAQ ruled rows → enrollment form → footer. Varied widths (full-bleed / boxed / narrow), ≥2 asymmetric sections, one card row only.
   Type      : Space Grotesk (display) / Inter (body) / Space Mono (numbers, formulas, data labels) — fluid clamp scale
   Color     : base #0F1016 / surface #171922 / ink #ECEEF5 / muted #8B8FA3 / accent magenta #E5399A / violet #8B5CF6 / lime #B6F09C (few data points)
   Motion    : scattered dots settle + distribution curve strokes in on scroll (transform/opacity only, reduced-motion stills)
   Signature : scatter dots + distribution curve + shaded variance band + mono formula chips — a consistent probability-lab visual language
   Hero-bg   : dark generated data-viz abstract (dots settling toward a curve) + animated CSS dot field + soft magenta/violet glow */
