design system

Tokens and components in one place.

A living reference of the colors, type, spacing, motion, and primitives this site is built from. Treat this page as the source of truth — if something on the site looks off, compare it here.

Typography

Inter for UI and body. Lora for headings. Monospace for code. Sizes follow a modular scale, leading scales independently.

Leading

leading-tight

Designers often spend disproportionate time on color and ignore line-height — yet leading shapes how comfortable a paragraph feels at a glance.

leading-snug

Designers often spend disproportionate time on color and ignore line-height — yet leading shapes how comfortable a paragraph feels at a glance.

leading-normal

leading-loose

Headings

Heading one — for the page title

Heading two — for major sections

Heading three — for subsections

Heading four — for inline groupings

Body and code

Body copy at the project default — 17px, leading 1.65, Inter. Inline code picks up the mono font and a subtle muted background.

tokens

Spacing

Derived from a single 0.25rem base. Use flex + gap for siblings, only use margin for prose flow.

Radius

All radius steps derive from a single --radius base (0.25rem). Change the base to reshape the whole UI.

Shadow

Tailwind's default shadow scale. Use sparingly — this system leans flat.

Motion

Hover each tile to play. Durations live close together so transitions feel cohesive; easings shape the perceived character.

Z-index

A small, semantically named scale. Use via style={{ zIndex: 'var(--z-modal)' }} to keep stacking decisions consistent.

Tracking

Letter-spacing scale from Tailwind defaults. Wide and widest are reserved for kicker / uppercase labels.

Card

Flexible container with optional header, action, and footer.

Plain card
A surface with subtle ring and rounded corners.

Cards inherit the popover token, so they sit one step above the page background in both themes.

With action and footer
The header grid auto-fits a CardAction on the right.

Body content. The footer below sticks to the bottom edge with a muted strip.

Accordion

Single-open by default; first item expanded.

A shared vocabulary — colors, type, spacing, components — that lets a team move quickly without re-deciding every detail.

Dialog

Modal surface, centered. Closes via overlay, escape, or X.

Trigger

Sheet

Side-anchored drawer. Each side is a separate variant.

Sides

Tooltip

Hover the trigger to reveal.

Hairline divider for both axes.
