When Neo.grid.Container instantiates its child components (GridBody, HeaderToolbar, FooterToolbar, and VerticalScrollbar) during construction, it properly passes down structural configs like parentId, store, and windowId, but it missed the initial theme value.

Because of this, if a Grid was created dynamically while the application was already in dark mode, these child components (and everything inside them) would render with the default light mode until a subsequent reactive toggle updated the global theme.

Resolution:

• Updated src/grid/Container.mjs to map theme: me.theme into the instantiation calls inside beforeSetBody, beforeSetFooterToolbar, beforeSetHeaderToolbar, and construct (for the scrollbar). This guarantees full visual consistency at birth.
