Color system

Dark surfaces use 7 repeated semantic colors; hierarchy is carried mainly by tonal contrast.

Canvas

Page canvas

Dominant rendered page background.
Surface 1

Surface

Repeated container or section fill; relative occurrence score 112.
Surface 2

Surface

Repeated container or section fill; relative occurrence score 100.
Surface 3

Repeated container or section fill; relative occurrence score 55.
Primary text

Primary text

Observed display foreground with 14.8:1 contrast against the captured canvas.
Secondary text

Secondary text

Observed reading foreground; measured canvas-reference contrast is 11.3:1.
Border

Border and divider

Most repeated inspectable border color.

Typography

The observed type system assigns Archivo to display, heading text; Inter to body, body-small text; JetBrains Mono to label text.

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

Run them anywhere. Leave them running.

Reproduction guidance

Do

  • Pair the observed #16161b canvas with #eae8ee primary copy before adding secondary surfaces.
  • Use Archivo at 105.6px/92.928px, weight 900, for the primary display moment.
  • Let the left-aligned type-led hero establish hierarchy before secondary content.
  • Typography and surface contrast carry the page; rendered imagery is minimal.

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 Archivo and Inter and JetBrains Mono.
  • Do not copy transition-all declarations; keep only purposeful transform or opacity motion.
