def build(data: pd.DataFrame, config: LineConfig) -> go.Figure:
    """
    Creates a Plotly line plot figure from a DataFrame and a Pydantic configuration.

    This function acts as a bridge between the abstract plot definition and the
    Plotly Express implementation. It translates the validated `LineConfig`
    into the arguments for `plotly.express.line` and also forwards any
    additional, unvalidated keyword arguments form plotly. The resulting figure
    is then customized with layout and theme settings using `plotly.graph_objects`.
    (https://plotly.com/python-api-reference/generated/plotly.express.line.html).

    Parameters
    ----------
    data : pd.DataFrame
        The DataFrame containing the plot data.
    config : LineConfig
        The validated Pydantic model with all plot configurations.

    Returns
    -------
    go.Figure
        A `plotly.graph_objects.Figure` object representing the line plot.
