• Consider clarifying in documentation whether coercing an undefined 'open' value to false is intended behavior for toggleDrawer.

toggleDrawer = (open: boolean | void) => {

packages/components/src/components/tabs/tabs.lite.tsx:145

• [nitpick] Consider explicitly typing the 'closest' function instead of relying on casting event.target to any to improve code clarity and maintainability.

const closest: | ((element: string) => HTMLElement | null) | undefined = (event.target as any)?.closest;

packages/components/src/components/custom-select/custom-select.lite.tsx:332

• Replacing the magic string 'close' with undefined and a forceClose flag improves clarity; verify that all handleClose calls are updated consistently.

state.handleClose('close');
