Operator · design system

The parts the panels are made of.

Every app-sample on the landing is built from the same small kit: a themed set of tokens, a handful of composable components, and the views that assemble them. Switch themes above; everything here reads from the exact CSS the app ships.

Elements

Tokens & type

Each theme is one block of CSS custom properties. Components never hard-code a colour. They reference these, so a theme swap re-skins everything at once.

Colour

html[data-theme="…"]

Values update live as you change theme. These chips read the resolved custom properties.

Sora sets headlines, Archivo carries prose, JetBrains Mono handles everything data: code, labels, metrics, timings.

Components

The kit

Small, composable pieces. Class names are shown beneath each so you can lift them straight from styles.css.

Panel shell

.panel · .panel-bar · .panel-foot

The frame every view sits in: a title bar with faux traffic lights, a body, and a metadata foot.

Tree rows

.tree · .row[style*="--d"] · .is-live

Depth is a CSS variable; the L-connectors and the live-row treatment are pure CSS.

Diff lines

.diff · .dhunk · .dline.add / .del

The one place we step outside the theme accent: add/remove use fixed green/red tokens, because that reads as “diff” everywhere.

Buttons

.btn-primary · .btn-ghost

Mono, uppercase, square-cornered. The primary is the only accent fill on the page; the ghost is a bordered echo of it.

The one house rule: “live” is shown with an accent left-border, a text flag, or a ticking value, never a pulsing/glowing status dot. That dot reads as a generic AI tell, so it stays out. The only animation-as-liveness we allow is a text caret (.caret) and the duration tick; both respect prefers-reduced-motion.
Motion

Liveness, not decoration

Motion here always means state change: a value ticking, text streaming, a row handing off. On the landing every panel loops its own small state machine while it is on screen, each on its own period, the way the mark's dots each twinkle on their own cycle. Panels pause when they scroll away; under prefers-reduced-motion the static markup is the whole experience.

Views

Assembled

The components composed into the real panels. These are lifted verbatim from the landing: the same markup, the same classes.
