Living design system
Design System
The Subframe-driven component library that powers this portfolio. Custom fonts (Erode + Satoshi), a brand cyan derived into a full 50 → 950 ramp, and 40+ synced components — all rendered here from the same source as the shipped site.
Foundations
Color & Type
Brand cyan derived through Subframe's Theme UI into a full ramp that survives every re-sync. Type overrides at the Tailwind layer so the codebase — not the design tool — owns the fonts.
Brand ramp — derived from hsl(153 100% 50%)
Display · Satoshi
Vision, shipped.
text-6xl · font-black · Satoshi Variable
Body · Erode (prose only)
Erode survives inside .prose paragraphs across feed, showcase, and case study pages, so reading still feels like a paperback. Everything else — buttons, badges, labels — snaps to Satoshi.
text-base · font-serif · Erode Variable
Section
Buttons & Actions
Ten Button variants (brand / neutral / destructive × primary / secondary / tertiary, plus inverse) at three sizes. IconButton and LinkButton round out the action surface.
Section
Forms & Input
Full input suite — TextField, TextArea, Select, checkbox, radio, switch, slider. Each accepts label, helper text, and error state props.
Section
Feedback & Status
Alerts, badges, progress, loaders, skeletons — the vocabulary the interface uses to admit what it knows and what it's still working on.
Section
Data & Structure
Tabs, accordion, stepper — patterns for organising dense product surfaces without losing the shape of the flow.
Notifications can be triggered by enrollment, completion, inactivity, or scheduled cadence. Add one trigger per notification for predictable delivery.
Section
Layout & Navigation
Wayfinding primitives — breadcrumbs, avatars, tooltips, and iconography — used consistently across every product surface.

How this system came together in one weekend
The custom-font override, the brand-token derivation, the pilot page, and the first component swap in production — all in a single weekend with Claude Code as pair-programmer.
