   BotNesia — Landing Page
   Original visual identity. No AI slop. Every pixel intentional.

   Design language: dark canvas, purple brand signal, cyan accent,
   green for positive states. Typography: Manrope (display + body),
   DM Mono (labels, metadata, code). 8pt spacing grid.

   Builds on /ui/styles.css design tokens (--bg, --brand, --cyan, etc.)
