Phials developer documentation

This section is for contributors and plugin authors: the plugin architecture, APIs, and how to ship extensions that run inside Phials.

Building plugins → - Overview, getting started, plugin types, lifecycle, and the public API contract.

Type references → - Auto-generated pages for every stable public SDK type.

Svelte & Phoundry UI → - The recommended UI stack for plugins, and why.

End-user guides (collections, vials, previews, settings) live in the Phials user doc set on docs.phoundry.app; use the site header to switch between user and developer docs.
