/* =========================================================
   BaVyx — Drizzle-inspired docs theme (independent rewrite)
   Brand: BaVyx | Path: /vy/ | Primary: #4F46E5 | Accent: #A78BFA + #FBBF24
   Layout takes its visual cue from 17_drizzle (dark left rail + light center
   + right partner column + bold step/table treatment), but every selector,
   color, and component is rewritten from scratch in BaVyx's own namespace
   (.vy-*) so it shares no CSS with babianx / babianvox / babianpeak.
