initThemeConfig method

@override void initThemeConfig(String configId, { BaseCommonConfig? currentLevelCommonConfig, })

部分代码示意如下：

cardTitleConfig.detailTextStyle.merge(
  BrnTextStyle(
    color: commonConfig.colorTextBase,
    fontSize: commonConfig.fontSizeBase,
  ).merge(detailTextStyle),
);

- 以 `commonConfig` 字段为基础 merge `detailTextStyle`。
  `detailTextStyle` 字段优先级高，当detailTextStyle中字段（如 color）为 null 时
  会使用 `commonConfig.colorTextBase`。
- 以默认上一级配置为基础 merge 第一步的结果，当第一步中字段（如 color）为空时，
  使用上一层级配置的 color (`cardTitleConfig.detailTextStyle.color`)。
