Primary text

Primary text

Observed display foreground; its canvas-reference contrast is 1.2:1 and may rely on a local hero surface.
Secondary text

Secondary text

Observed reading foreground; measured canvas-reference contrast is 16.8:1.
Action

Primary action

Foreground used by the dominant first-viewport action.

Typography

The observed type system assigns Instrument Serif to display text; Schibsted Grotesk to heading, body text; Geist Mono to body-small text; Sans Serif to label text.

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

Imagery, motion & responsive

Imagery

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

Reproduction guidance

Do

  • Pair the observed #eeeeee canvas with #ffffff primary copy before adding secondary surfaces.
  • Use Instrument Serif at 44px/56px, weight 400, for the primary display moment.
  • Reserve the strongest first-viewport contrast for “reserve early access” within the center-aligned stacked hero.
  • Image led media acts as the page’s primary visual proof rather than decoration.

Don’t

  • Do not mix in arbitrary radii; 6px is the repeated treatment on containers.
  • Do not reuse the #0000ee action color across decorative elements; keep its interactive emphasis selective.
  • Do not introduce extra type families beyond Instrument Serif and Schibsted Grotesk and Geist Mono and Sans Serif.
  • Do not spread the observed shadow treatment across every container; keep elevation selective.
