Do

  • Use 'arcadiaDisplay' at a light weight (360) for all major headlines to maintain an airy, sophisticated tone.
  • Reserve the 'Mercury Blue' (#5266eb) accent exclusively for primary, action-oriented CTAs.
  • Employ the deep neutral palette (#171721, #1e1e2a) for all backgrounds to create a focused, immersive environment.
  • Utilize extreme corner radii (32px, 40px) for all primary and secondary buttons, creating a signature 'pill' shape.
  • Maintain high contrast with 'Starlight' (#ededf3) text on dark backgrounds for all primary content.
  • Use generous vertical spacing (80px+) between content sections.
  • Differentiate interactive list items with a simple 1px bottom border in 'Lead' (#70707d).

Don't

  • Don't use 'Mercury Blue' (#5266eb) for text, backgrounds, or decorative elements.
  • Don't use heavy font weights (>530) for any typography.
  • Don't apply shadows for elevation. Use color and opacity shifts instead.
  • Don't introduce new saturated colors. The palette is monochrome plus one blue accent.
  • Don't use small corner radii on buttons. They should always be pills.
  • Don't use 'Pure White' (#ffffff) for body text; reserve it for text on the primary blue CTA.
  • Don't create dense, cluttered layouts. Prioritize breathing room.
