FOUNDATIONS

No pixel without
a passport.

3,491 CSS custom properties. Every visual value resolves through the chain — component → semantic → primitive — and components may never touch a raw value. That's why dark mode costs zero component code.

THE CHAIN

Three layers, one direction

A component asks for meaning. Meaning asks for a value. Only the bottom layer knows what a hex is.

component layer
--oi-button-primary-bg
what this component's surface is called
→
semantic layer
--oi-bg-brand
what the value means, anywhere it appears
→
primitive layer
--oi-color-teal-600 #1daf9c
the only layer allowed to hold a raw value
⛔ Rule 4A primitive referenced in component CSS = build failure. No hex, no primitives, no Ant token.* — ever.

visualization palette — 15 slots · data only, NEVER chrome
Teal is the only chrome accent. Everything else on screen that has a color is data.
TYPOGRAPHY

Two families, one law

Inter carries the UI. IBM Plex Mono carries data — IDs, timestamps, code, metrics. Mono is never a label and never a heading.

INTER

The interface voice

Headings, labels, paragraphs, buttons, navigation — everything a human reads as language.

IBM PLEX MONO

the data voice

Run IDs, timestamps, token names, code, metric values — everything a human reads as data.

Brick spacing math

The canvas breathes on a fixed rhythm — no component decides its own margins.

canvas edge 24px = row 12 + wrapper 12
between bricks 24px
between rows 12px
CONTROL HEIGHTS

The closed scale

Four heights. Not a suggestion — a closed set.

sm · 24px
md · 32px · DEFAULT
lg · 40px
xl · 48px
⚠ xl: hero pickers only. 28 / 36 / 44 do not exist.
MOTION & FEEL

Two curves for everything

SPRING

--oi-motion-spring

280ms cubic-bezier(0.34, 1.56, 0.64, 1)

Entrances, hovers, anything that should feel alive — a slight overshoot, never a bounce.

SNAP

--oi-motion-snap

140ms cubic-bezier(0.4, 0, 0.2, 1)

State changes, toggles, tab switches — instant confidence, no theater.

The modernization vocabulary in one control: inset top highlight → depth, teal glow halo on hover, focus ring for keyboards, scale(0.98) on press.

Dual theme via [data-theme] — every semantic token carries a light and a dark value. Flip the attribute, the whole product follows. Components never notice.
