Structured content
Sveltia exposes a controlled set of reusable blocks instead of arbitrary layout controls.
Polysemic core 0.1
Structure first. Style without limits.
An accessible Astro starter whose content, behavior and visual identity stay cleanly separated.
Managed foundation
A small core with deliberate boundaries.
Each client inherits tested behavior while keeping its own theme and room for custom blocks.
Accessible behavior
Bits UI owns keyboard navigation, focus management and ARIA behavior for interactive primitives.
Fast styling
UnoCSS generates only the utilities used by the site while semantic variables define the client theme.
Static by default
Astro ships HTML and CSS for ordinary sections, hydrating only components that need interaction.
Canary checks
What this starter proves.
Yes. Branding lives in the client-owned theme file while managed components consume stable semantic variables.
No. Astro blocks remain static. Only interactive Bits UI wrappers receive a client hydration directive.
Yes. Sveltia stores the page as an ordered list of typed blocks without exposing implementation classes.
Ready for a real client identity.
Replace the reference theme, edit the content in Sveltia and extend the block registry only when the project requires it.
This paragraph is ordinary Markdown content. It remains available after the structured blocks for long-form material that does not need a custom layout.
