无法使用@use导入SCSS变量文件，寻求解决方法

尝试用@use引入包含变量的_variables.scss文件时失败，但导入不含变量的其他SCSS文件正常。

文件结构 #

问题出在@use的核心规范上：和旧的@import不同，@use导入的模块中，变量、混合宏、函数必须通过命名空间访问（默认命名空间是文件名去掉下划线和后缀）。你的代码直接使用$soft-color、color()等标识符，SCSS无法定位到来源模块，导致导入失效。

具体修复步骤： #

1. 变量前添加命名空间：
   把$soft-color改为variables.$soft-color，$card-color改为variables.$card-color，所有来自_variables.scss的变量都要加上variables.前缀。

2. 函数、混合宏前添加命名空间：
   把color(bg, hero)改为variables.color(bg, hero)；如果使用混合宏@include shadow()，要改为@include variables.shadow()。

3. （可选）自定义简化命名空间：
   可以在导入时指定别名，减少代码长度：

   @use "variables" as v;
   

   之后就可以用v.$soft-color、v.color(bg, hero)来访问模块内容。

修复后的主SCSS片段示例： #

@use "header";
@use "layout";
@use "variables";

/*  Hero section  */
.hero {
  width: 100%;
  position: relative;
  background-color: variables.color(bg, hero);
  &::before {
    background: linear-gradient(
      to right bottom,
      variables.color(bg, hero) 50%,
      transparent 50%
    );
  }
  .card-wrapper {
    .card-info {
      .content {
        .box {
          border-bottom: 1px solid variables.$soft-color;
        }
      }
      .card-image {
        background-color: variables.$card-color;
        .details {
          .flex {
            div {
              h4 {
                color: variables.$text-white;
                font-weight: variables.$fw-400;
              }
            }
          }
        }
      }
    }
  }
  // ... 其余代码按相同规则替换
}

另外确认路径：从文件结构看，_variables.scss和主文件在同一目录，@use "variables";的路径是正确的，无需调整。
