 /**
- * 显示设置：全局字体大小档位（仅字号，不含整体缩放/字体族）。

- * 实现原理：Tailwind 4 的 `text-*` 字号类均为 rem 单位（如 text-sm = 0.875rem），
- * 因此修改根元素 `html` 的 font-size 即可让全部 rem 字号类联动缩放。
- * 取值范围：14px(小) ~ 18px(特大)，默认 16px(标准)。
+ * 通过 Electron 的 setZoomFactor 整体缩放渲染内容，连图标、间距、布局
+ * 一起等比放大/缩小（逻辑分辨率变化），不会破坏布局；与单纯改字号相比
+ * 更稳定，故本应用只提供此一种显示放大入口。
  *
- * 持久化：localStorage key = "spark-store-font-size"，存档位枚举字符串。
