Design system / v0.1
Product Room System
Small system. Big impact.
This portfolio is the working example. The foundations below feed its styles; the specimens render the same React components used on the homepage. A focused library for a specific product, with decisions you can inspect.

Change modes, not moods.
Compare the palette, typography, and components in light or dark. System follows your device; your choice applies across the site.
01 / Foundations
Each token has a job to do.
The colors change. Their purpose stays the same.
Navy and ivory trade places between appearances, while each color keeps its role. Violet identifies the primary action; its darker fill keeps small white labels readable. Orange marks keyboard focus, with a deeper shade on light surfaces. Borders divide content without introducing another card around everything.

02 / Typography + rhythm
Typography
Geist and IBM Plex Mono
Headings use the strongest ink, subtitles step down, and body copy is slightly muted. Reading copy uses a steady 16px size and generous line height across every page. Titles scale with the viewport. Labels, navigation, links, and buttons share mono; emphasis comes from placement and weight, rather than another font size.
Clarity through structure.
Related thoughts stay together.
Enough room to read, enough structure to scan. Each paragraph develops one idea, with a measure that stays comfortable as the screen gets wider.
Explore the full typography reference
The role determines color, size, and rhythm. Heading size responds to its context; body, caption, subtitle, and label roles are shared across every page.
abcdefghijklmnopqrstuvwxyz
0123456789 & @ ! ? ( )
abcdefghijklmnopqrstuvwxyz
0123456789 / : ; →
A supporting line stays close to the heading it explains.
Body copy carries the story in a slightly muted tone. A comfortable line length gives each idea enough room to develop without stretching across the whole screen.
A new paragraph starts a new thought. Emphasis can be strong or italic without introducing another text size.
Supporting context, figure descriptions, and specimen notes use the caption role.

- Subtitle

- Body + caption

Use semantic heading levels for document structure. Use body for narrative, caption for supporting context, and mono labels for interface metadata. Text wraps naturally; avoid fixed-height containers that clip enlarged text.

03 / Actions
It should be clear what happens next.
Different actions, a familiar set of controls.
Links navigate. Buttons perform an action. Both share the same variants, a 44px minimum height, and mono labels. Visual emphasis is separate from behavior: StudioLink navigates, while StudioButton performs an action. Destructive identifies a consequence, rather than a level of emphasis.
Each variant appears enabled first, then disabled.
primary
The main next step. Give it priority within its group.
secondary
A quieter alternative with a filled surface.
outline
A bounded action without a filled surface.
ghost
A borderless control with a hover surface. Its transparent border preserves spacing.
text
A quiet text action without a container or underline.
link
An underlined treatment, often used for navigation.
destructive
An action that removes data. Its label states the consequence.
These are interactive specimens. They do not save or delete data.
Hover changes the surface; Tab reveals the orange focus outline. Disabled buttons retain their dimensions and cannot activate. Reduced-motion preferences remove transitions. Open the source below to try a real secondary button: Copy source.
Every element should feel at home.
Appearance uses the shared StudioSelect component. The menu follows the active palette, with a check for the selected value and a distinct keyboard highlight. Arrow keys move through choices; Enter selects and Escape closes.
Inspect select.tsx — the shared Radix select

return <button type={type} className={cn('studio-action', `studio-action-${variant}`, className)} {...props} />;
}
04 / Composition
Spacing helps tell the story.
Keep related thoughts together. Give new ones some room.
The homepage and these section openings use SectionIntro. The label introduces a subject, the subtitle stays close to its heading, and supporting copy sits in its own group. The example below is the component itself.

Show the idea. Open the detail.
Work introduces each chapter with a short headline, a vector illustration, and one path into the full story. The same alternating composition can introduce other subjects. Screens keep their original proportions, while gentle motion pauses offscreen and respects reduced-motion preferences.

05 / Build + scope
This is the system the site actually uses.
Next.js App Router · React · CSS custom properties
The library lives beside the interface it serves. This page reads the token and component files on the server at build time, so the source shown here comes from the same revision as the site.
src/app/tokens.cssFoundations
Named color, spacing, type, and motion values. The root layout imports these before the component styles. Geist and IBM Plex Mono are loaded through next/font.
src/components/studio/Shared interface
StudioLink and StudioButton preserve native element behavior. SectionIntro owns the heading relationships. These components render directly in the homepage and this reference.
src/app/studio.css + system.cssResponsive composition
The rail becomes mobile navigation at 760px. The homepage hero stacks at 1000px. Content groups reflow while keeping their internal spacing and reading order.
src/app/system/page.tsxServer by default
The reference is a server-rendered page. Appearance controls and source copying use client state. Dark is the default; a saved preference is applied before the first paint, and System responds to your device setting. Native disclosure elements handle code examples.
Where this stands
Every page uses the same heading, subtitle, body, caption, and label roles in both appearances. The homepage and this reference also share SectionIntro. Work, About, and Contact keep layouts suited to their content; forms and galleries are specialized patterns rather than a separate typography system.
