Design guidance

Do's and Don'ts

**Do**

  • Do use primary pink (#de3f7d) exclusively on CTAs and high-priority interactive elements—never on passive content or backgrounds.
  • Do apply negative letter-spacing (-0.02em to -0.04em) to all GT America Compressed headlines to reinforce the technical, engineered aesthetic.
  • Do maintain minimum padding of md (24px) on all cards and containers to ensure visual breathing room and professional appearance.
  • Do use the navy-gray shadow color (rgba(30, 39, 66, ...)) for all elevation effects to maintain the cool, sophisticated tone.
  • Do transition all interactive state changes (hover, focus, active) over 200ms with ease-in-out timing for smooth, predictable feedback.
  • Do pair Open Sans body text with GT America Compressed headlines to create visual tension that communicates both precision and approachability.

**Don't**

  • Don't use primary pink on passive elements, backgrounds, or non-interactive content—reserve it for actions and CTAs only.
  • Don't mix border-radius values arbitrarily; use the defined scale (sm, DEFAULT, md, lg, xl, full) to maintain visual consistency.
  • Don't apply shadows darker than lg (0 8px 24px rgba(30, 39, 66, 0.2))—the system is deliberately flat and modern, not skeuomorphic.
  • Don't use pure black (#000000) or pure white (#ffffff) for text; use on-surface (#323857) for primary text and on-surface-variant (#6b7280) for secondary to maintain sophistication.
  • Don't transition colors instantly; always use 200ms ease-in-out for hover, focus, and active states to provide smooth, professional feedback.
  • Don't override the typography scale with arbitrary font sizes; use the defined levels (display, headline-lg, body-md, label-sm) to maintain hierarchy and readability.
