%% 重新定义 \__codedoc_typeset_function_block:nN: 将函数本体与其后方
%% \__codedoc_typeset_TF: 并入 \l__ctxdoc_function_block_box, 并根据情况进行压缩.
%% 相比 l3doc 对 variable 和 macro 采用的 2/3 倍压缩, 这里采用更灵活一些的方式.
%% ### 分段式压缩函数
%% A. 正比弹性范围: 3 档均匀压缩
%% 设定一个整数变量 \l__ctxdoc_function_block_scale_frac_int 初始值为 6.
%%   * 第 1 档缩放到当前宽度的 5/6, 累计为原宽的 5/6, 对整数变量减 1.
%%   * 第 2 档缩放到当前宽度的 4/5, 累计为原宽的 2/3, 对整数变量减 1.
%%   * 第 3 档缩放到当前宽度的 3/4, 累计为原宽的 1/2, 对整数变量减 1.
%%   * 若继续压缩辨识度将大幅下降, 均匀压缩到此截断. 建议简化函数名!!
%% B. 非均匀强行压缩
%% 3 档均匀压缩后若函数宽度仍超出阈值, 则采用自适应到可用左侧列宽并广播 note 型警告.
%% 循环 \dim_while_do:nNnn 在函数宽度大于参照长度时压缩; 两者相等即停止.
%% ### 参照长度计算
%% 计算方法为左侧旁注宽度与扣除宽度之差
%%     \marginparwidth - \l__ctxdoc_function_block_decr_dim
%% 其中扣除宽度中包含
%%   * \marginparsep 保证两侧空隙对称
%%   * EXP  选项: 额外扣除宽度 =  wd($star$)    + 6.0pt for colsep
%%   * rEXP 选项: 额外扣除宽度 =  wd(\ding{73}) + 6.0pt for colsep
%% 为代码简洁, 列间距 + 6.0 pt 通过 \bool_case:nTF 的 T-branch 共享拼接.
%% 若 l3doc 新增可展性类别, 需在此同步补充其右栏预留宽度.
%% 设置 \l__ctxdoc_function_block_decr_dim 为 \marginparwidth 的相反数,
%% 即此时循环对比长度为 2\marginparwidth, 以确保退出循环.
%% ### 重定义的后续跟进
