crates/openshell-tui/src/ui/mod.rs:492–500

Render an empty-state message inside a bordered panel. Calculates an inset [`Rect`] that clears the panel border and renders `text` with the given `style`. Use this whenever a table or list has no rows to display.

(frame: &mut Frame<'_>, area: Rect, text: &str, style: Style)

/// `text` with the given `style`.  Use this whenever a table or list has no
/// rows to display.

    let inner = Rect {
        x: area.x + 2,
        y: area.y + 2,
        width: area.width.saturating_sub(4),
        height: area.height.saturating_sub(3),
    };
    frame.render_widget(Paragraph::new(Span::styled(text, style)), inner);

/// Center a popup rectangle within `area` using absolute width and height (in
/// terminal columns/rows).
