The shell container. Owns the shared border, surface, radius, and hover treatment that every card on the site inherits. Link-agnostic — wrap it in whatever element your context needs. Four variants provide flexibility across surfaces.

<Card>
  <p>Default variant — surface, border, 1.5rem padding.</p>
</Card>

<Card variant="bordered">
  <p>Bordered — transparent fill, keeps the border.</p>
</Card>

<Card variant="ghost">
  <p>Ghost — transparent, no border, no visible chrome.</p>
</Card>

<Card variant="compact">
  <p>Compact — smaller padding for dense layouts.</p>
</Card>

Composed on top of Card. Adds the status badge, display-type title, role, version, and protected-route metadata pattern used for project entries.

<ProjectCard
  title="PayPal Design System"
  role="Design Lead"
  v="3.2.0"
  status="stable"
  href="/components/paypal-ds"
/>

A compact protected-route signal. It continues metadata with an interpunct and exposes a Locked label to assistive technology.

<LockIndicator />
<LockIndicator separator="interpunct" />

Lifecycle indicator: stable, beta, or deprecated. Used to communicate the maturity of a doc page, a project, or a primitive itself.

<StatusBadge status="stable" />
<StatusBadge status="beta" />
<StatusBadge status="deprecated" />

Numbered section heading with a trailing rule. Chunks long docs pages into ordered sections — used throughout the site (you're reading them now).

<SectionLabel n="01">Example section</SectionLabel>

A statistic cell, composed by StatGrid into responsive collections. Three values stack on mobile, then become an equal three-column row from the medium breakpoint.

<StatGrid
  items={[
    { k: "Tenure", v: "4+ yrs", sub: "at PayPal" },
    { k: "Role", v: "Lead", sub: "Design Systems" },
    { k: "Components", v: "200+", sub: "shipped" },
  ]}
/>

A grid of design tokens with hover-to-inspect value behavior. Reads from the live computed styles, so it stays accurate across light and dark mode.

<TokenStrip />

Live-sandbox frame for documenting other primitives. Wraps children in a grid-bg surface and intercepts click events so demoed interactions don't fire navigation away from the docs page. You're looking at one right now in every primitive's Preview tab on this page.

<Preview>
  <Card>Hello</Card>
</Preview>

Composable tab navigation with a sliding underline indicator. Used on every primitive section on this page, and on project case-study pages. Radix-style composition — Tabs owns the state; TabList, TabTrigger, and TabPanel compose into it.

<Tabs defaultValue="preview">
  <TabList>
    <TabTrigger value="preview">Preview</TabTrigger>
    <TabTrigger value="props">Props</TabTrigger>
    <TabTrigger value="code">Code</TabTrigger>
  </TabList>
  <TabPanel value="preview"><Preview>…</Preview></TabPanel>
  <TabPanel value="props"><PropsTable rows={…} /></TabPanel>
  <TabPanel value="code"><pre>…</pre></TabPanel>
</Tabs>

Shell-only table primitive. Owns the wrapper border, rounded corners, mono typography, horizontal scroll behavior, and header/row styling via descendant selectors. Consumers write standard thead and tbody markup inside. Used by the Props panels on this page and on project case-study pages.

<Table minWidth="520px">
  <thead>
    <tr>
      <th>Prop</th>
      <th>Type</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>children</td>
      <td className="opacity-70">ReactNode</td>
    </tr>
  </tbody>
</Table>

Pre-formatted code snippet with an inline copy-to-clipboard button. Used in every Code panel on this page and on project case-study pages. Click the copy icon in the top-right to copy the snippet; icon swaps to a check on success.

<Card>
  <p>Hello</p>
</Card>

<CodeBlock>{`<Card>
  <p>Hello</p>
</Card>`}</CodeBlock>

Horizontal scroll surface that refreshes only its own rendered layer when the theme changes, preventing previously hidden content from retaining stale colors. It preserves horizontal scroll position and leaves surrounding page and tab state alone.

theme-aware scroll content → → → → → → → → → → → → → → →

<ThemeScrollArea
  as="pre"
  className="overflow-x-auto p-4"
  style={{ background: "var(--surface)" }}
>
  {json}
</ThemeScrollArea>

Mono-styled text input with consistent border, focus, and disabled treatment. Forwards all native input props through, so it supports type, placeholder, value, onChange, disabled, and the rest. States shown below: default, filled, and disabled. The focus state — a border highlight on the active input — appears when you click into any field above.

<Input
  type="password"
  value={password}
  onChange={(e) => setPassword(e.target.value)}
  placeholder="Password"
  autoFocus
/>

Three variants for three levels of emphasis: primary (solid ink fill, top-priority CTAs), secondary (quiet ink-wash fill, alternative actions), tertiary (text-only, quiet links). size="small" keeps compact controls aligned with the system; medium is the default. Three rendering modes via polymorphism: button (default), Link (when href is passed), or span (when asLabel is true — for use inside a parent interactive element, like the channel CTAs inside contact card links). External links (target="_blank") automatically append an ArrowUpRight icon — no manual icon needed.

import { Key } from "lucide-react";

// Primary — form submit action
<Button variant="primary" type="submit" disabled={loading}>
  {loading ? 'Checking…' : (
    <span className="inline-flex items-center gap-2">
      <Key size={14} aria-hidden="true" />
      <span className="translate-y-px">Unlock</span>
    </span>
  )}
</Button>

// Secondary — alternative action
<Button variant="secondary" onClick={onCancel}>Cancel</Button>

// Compact primary and secondary — inline or canvas controls
<Button variant="primary" size="small">Unlock</Button>
<Button variant="secondary" size="small">Cancel</Button>

// Tertiary — internal navigation; ArrowRight appended automatically
<Button variant="tertiary" href="/changelog">
  View full changelog
</Button>

// Tertiary — external link; ArrowUpRight appended automatically
<Button variant="tertiary" href="https://github.com" target="_blank" rel="noopener noreferrer">
  GitHub
</Button>

// asLabel — non-interactive visual, renders as <span>
// Use inside a parent interactive element (e.g. channel CTAs in card links)
<Button variant="tertiary" asLabel className="group-hover:opacity-100">
  Open mail
  <ArrowUpRight size={12} />
</Button>

Wraps any high-value canvas surface with an expand-to-fullscreen interaction. The expanded canvas opens as a portaled dialog with Motion transitions, focus management, and reduced-motion support. An optional controls slot accommodates per-surface UI, while virtualViewport fits authored responsive compositions to mobile and desktop reference widths.

<CanvasShell
  id="project-preview"
  title="Project preview"
  contentAlignment="start"
  virtualViewport={{ mobileWidth: 390, desktopWidth: 1920 }}
>
  <ProjectPreview />
</CanvasShell>

A masked entrance for display copy. The default reveals authored lines in sequence; the letter wave follows every semantic Instrument Serif display headline's rendered lines.

import DisplayHeadline from "@/components/ui/DisplayHeadline";

<DisplayHeadline className="text-display-xl">
  Foundation before flourish.
</DisplayHeadline>

A clipped upward entrance for a single content block. It is the shared reveal treatment for the intro's supporting elements.

import MaskReveal from "@/components/ui/MaskReveal";

<MaskReveal>
  <SectionLabel n="01">At a glance</SectionLabel>
</MaskReveal>

A one-shot fade and rise for section-sized content as it enters the viewport.

import ViewportReveal from "@/components/ui/ViewportReveal";

<ViewportReveal as="section" depth="section">
  <SectionLabel n="01">Section name</SectionLabel>
  {/* content */}
</ViewportReveal>
