Elevation is intentionally restrained because the library ships behavior and accessible structure rather than a visual theme.
| Token | Use |
|---|---|
--hui-shadow-none | Flat surfaces and the default state. |
--hui-shadow-sm | Small raised controls or cards. |
--hui-shadow-md | Popovers and menus. |
--hui-shadow-lg | Dialogs, overlays, and prominent transient UI. |
Use elevation together with a surface and border role; do not rely on shadow alone to communicate a boundary. The upstream shadow primitives are --ds-elevation-shadow-*.
