Light Theme

Returns a light theme. All parameters have sensible defaults; most users only need base_font_size. Title font size defaults to 1.2x the base; all other text defaults to 1x. Data-zoom sliders use neutral gray controls, including their data preview and hover states. Explicit component styles override these theme defaults.
