Answer 1

export default is default export, as the name implies. Regardless of how the variable that holds a value of default export is called, it's supposed to be imported as default import, not named import with brackets:
const legend = ...;
export default legend;
and
import legendCanBeImportedUnderAnyName from "/src/legends.js"
Alternatively, it can be made named export, it also needs to be imported as such:
export const legend = ...;
and
import { legend } from "/src/legends.js"

Answer 2

Try this.import * as legend from "/src/legends.js";
