Border

Typography

The observed type system assigns Instrument Serif to display, heading text; Newsreader to body, label text.

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

Reproduction guidance

Do

  • Pair the observed #e8ebe7 canvas with #17201c primary copy before adding secondary surfaces.
  • Use Instrument Serif at 84px/82.32px, weight 400, for the primary display moment.
  • Reserve the strongest first-viewport contrast for “Magmatize your data →” within the left-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; 50px is the repeated treatment on pills.
  • Do not reuse the #17201c action color across decorative elements; keep its interactive emphasis selective.
  • Do not introduce extra type families beyond Instrument Serif and Newsreader.
  • Do not add card shadows; the source separates content without repeated elevation.
