We’re excited to introduce full Custom Theme support — giving you complete control over the visual design of your projects.

Theme Config Basics

You can now define your design system using a centralized theme config file. This includes:

• Color palettes: Set primary, secondary, background, and surface colors.
• Typography: Customize font families, weights, sizes, and line-heights.
• Spacing: Define spacing tokens for consistent layout control.
• Radius & borders: Apply border radii and strokes across components.

Themes are structured, versionable, and live in your repo — making it easy to reuse or extend them across multiple sites or workspaces.

Scoped or Global

Themes can be applied:

• Globally to your entire site.
• Scoped to specific sections, pages, or components.
• Switched dynamically at runtime via a theme picker.

This makes it simple to support light/dark modes, customer branding, or white-labeled layouts.

Developer Experience

• Built-in schema validation to catch errors early.
• Autocomplete support in most editors.
• Optional TypeScript definitions for strongly typed themes.

Use Cases

• Build a client site with their exact brand guidelines.
• Switch themes for seasonal campaigns or product launches.
• Enable your team to collaborate with shared design tokens.

This update gives developers and designers a shared language to work from — flexible enough for rapid prototyping, powerful enough for production.
