Usage

When to use

Use it to build predictable page, toolbar, panel, or grid structure.
Keep layout primitives responsible for geometry and let child components own behavior.

Implementation notes

Stylesheet Import @duskmoon-dev/components/styles.css once in the app or docs shell.

State Start with default props for static examples, then switch to controlled props when state must be shared.

Theme The preview inherits the active DuskMoon data-theme value from the docs layout.

Features

Composition primitive

Documents spacing, responsive behavior, and nested regions used to build larger screens.

Stable geometry

Examples keep predictable dimensions so the surrounding UI does not jump while content changes.

Primary API surface

Splitter is most often configured through `layout`, `sizes`, `defaultSizes`, `onResize`.

Covered behavior

Renders horizontal panels with default sizes

Feature Demos

Feature demos are authored for the component page, then supplemented with behavior scenarios from the component test coverage.
