- WordcloudOptionBuilder: shape, font size range, rotation range,
grid size, font family/weight, 3 color modes (palette/random/gradient)
- WordcloudConfig panel: full UI for all wordcloud settings
- StyleConfig: conditionally shows wordcloud/axis/legend panels
based on chart type (wordcloud hides axes, KPI hides legend, etc.)
