"""得分.json → 单文件 HTML 记分卡（模板 scorecard_template.html）。

沿用技能盘面图的品牌风格：logo 与品牌字体从母版 scripts/render/assets/
以 base64 内嵌（单文件便携），亮色卡片风。数据全部由 得分.json 注入，
模板不含任何硬编码分数。

得分.json 字段 schema（收录新模型时按此填写）：
    model, skill_mode（with-skill / without-skill）, skill_version, eval_date,
    benchmark,
    overall:      {total, correct, accuracy, no_answer}
    baseline:     {name, overall: {total, correct, accuracy},
                   per_contest: {contest: accuracy}, per_dimension: {维度: accuracy}}
    per_contest:  {contest: {total, correct, accuracy, no_answer}}
    per_dimension:{维度: {total, correct, accuracy, no_answer}}

用法：
    python render_scorecard.py [--score <得分.json>] [--out <输出.html>]
                               [--template <模板>] [--assets <render/assets>]
默认：--score 评测/ai模型纬度得分/kimi-k3/with-skill/得分.json，
输出与得分.json 同目录的 得分.html。
