Primary text

Secondary text

Secondary text

Observed reading foreground; measured canvas-reference contrast is 5.2:1.
Border

Border and divider

Most repeated inspectable border color.

Typography

A single-family system uses Outfit across display and reading roles, differentiated by size and weight.

Metric previews use the observed CSS values. Source font files are not bundled, so unavailable families fall back locally.

Imagery, motion & responsive

Imagery

Video led media acts as the page’s primary visual proof rather than decoration.

Composition

Reproduction guidance

Do

  • Pair the observed #f3f1e9 canvas with #153347 primary copy before adding secondary surfaces.
  • Use Outfit at 120px/117.6px, weight 400, for the primary display moment.
  • Let the left-aligned visual-led hero establish hierarchy before secondary content.
  • Video led media acts as the page’s primary visual proof rather than decoration.

Don’t

  • Do not mix in arbitrary radii; 50px is the repeated treatment on pills.
  • Do not introduce an accent hue that is absent from the captured palette.
  • Do not introduce extra type families beyond Outfit.
  • Do not add card shadows; the source separates content without repeated elevation.
