/* Expected Lab — Design DNA
   Direction : chalkboard academic — deep-green board texture, chalk-white ink, hand-drawn SVG diagrams, warm & friendly
   Layout    : boxed 1080 reading spine with deliberate width shifts (full-bleed board bands, narrow measures, 2 asymmetric 60/40 & bleed-split)
   Type      : Gloock (display serif) / Inter (text) / Space Mono (formulas & numbers) — fluid clamp scale
   Color     : #1f2b25 board / #24332c surface / #eef2ea chalk ink / #e9c46a chalk-yellow accent (60-30-10, OKLCH-reasoned)
   Motion    : chalk lines draw-in (stroke-dashoffset) + count-up, restrained 400–900ms, full reduced-motion off-switch
   Signature : hand-drawn chalk SVG diagrams (probability tree / distribution curve / d6 outcome grid) + mono formula chips
   Hero-bg   : bespoke chalkboard texture (layered noise/vignette) + a drawn chalk probability tree */
