~/system — live

Design system, in production.

Every primitive on this page is imported from the same module that renders the rest of the site. If a chip looks different here than on the home hero, the system is broken — that's the contract. Switch the theme in the topbar to see light/dark tokens swap.

01 · Color tokens

Every surface, ink, and accent on the site flows through these CSS variables. Switch theme to see them reflow.

--bg
page background
--bg-2
window surface
--panel
card surface
--panel-2
hover / pressed surface
--ink
primary text
--ink-soft
secondary text
--ink-mute
meta / placeholder
--stroke
panel borders
--accent
primary accent
--accent-2
secondary accent
--warn
warning / amber
--danger
danger / red
--gold
gold / strings in code

02 · Typography

Inter for body, JetBrains Mono for code + UI captions. Display headlines use Inter at variable weight with tight tracking.

03 · Buttons

Primary (accent fill), ghost (panel + stroke), disabled, and icon-only. All meet keyboard + focus contracts.

05 · Motion primitives

All motion respects prefers-reduced-motion globally. Hover/focus transitions stay under 200ms.

pulse
@keyframes pulse · 2s loop · honors prefers-reduced-motion
blink
@keyframes blink · steps(1) · terminal cursor
lift
translate-y(-2px) · 150ms · used on icon links + cards
focus ring
2px solid accent · offset 2px · global :focus-visible

06 · Icon links

Profile-link primitive — same component used in the hero panel.

07 · Tagline parser

Inline tokens: **bold** renders as ink emphasis, *mono* renders as accent code chip. Same component as the hero.

Senior full-stack — React, TypeScript, Next.js up front and Python / FastAPI behind. I've shipped at Apple, Smartsheet, and Amperity.

08 · Terminal · code blocks

The whoami terminal from the hero. Syntax tokens (key, str, num, comment) all switch with theme.

~/profile.json — terminal
