LGTM!

Instead of being forced to as string each of these, I think we can fix this more cleanly by moving the type annotation for strings from:

export const strings: {
    [key in keyof PerseusStrings]:
        | string
        | {context?: string; message: string}
        | {context?: string; one: string; other: string};
} = {
    closeKeypad: "close math keypad",
    ...
};

to:

export const strings = {
    closeKeypad: "close math keypad",
    ...
} satisfies {
    [key in keyof PerseusStrings]:
        | string
        | {context?: string; message: string}
        | {context?: string; one: string; other: string};
};

Using satisfies instead of : mytype = means that we allow TypeScript to infer the type of each key in strings, but the entire structure must conform to the satisfied type. So TypeScript can now infer that strings has a closeKeypad key with a string value instead of a value that is one of string {context..} etc.
