/* ============================================================
   recap.study — Site Stylesheet
   Card-block design system · 2025
   
   STRUCTURE (unchanged):
   body > .ads_top / main (flex-row) > aside + #articleBody (flex-row) > article + aside / footer
   
   DESIGN LOGIC:
   · Page background: neutral dot-grid, same as card system
   · aside (left nav) = card block — tinted background, top border accent
   · article = main card — white body, strong header rule
   · footer = subdued card block
   · Nav buttons: card-style, matching lens palette
   · Typography: Merriweather for body, system sans for UI elements
