 ### Added
 
+- the swatch is resolved in an effect, and the ref is actually ON the element. Both got broken while editing this and nothing failed: a ref that is not attached reads as null, the effect returns early, and `?? "#000000"` does the rest — so a fallback that HIDES a missing ref is itself part of the defect. jsdom does not resolve `color` into `getComputedStyle`, so the inherited branch is only observable in a browser; what the test pins is the contract that let it slip, namely that the swatch is never handed the literal string.
+
 - the swatch is resolved in an effect, not from a ref. A ref is null during the render that needs it, so the first version always fell through to black — a swatch reporting black for dots that are not black — and `input[type=color]` silently ignores a non-hex value, keeping a stale colour instead. There is now a test that the swatch is always handed a form it will render.
 
 - **The dot colour is selectable, and it copies.** A picker in the sticky pane beside the field it colours — a native swatch with the OS colour well and the eyedropper, a text field, and HEX / RGB / HSL chips. The colour reaches the copied snippet, which it did not before: `changedOptions` never emitted `color`, so a visitor who picked a colour and pasted the result got a component that drew in `currentColor` and no indication why.

 ### 新增
 
+- 色块在 effect 里解析，而且 ref 确实挂在元素上。两者都在编辑过程中被弄坏过，且没有任何检查失败：没挂上的 ref 读出来是 null，effect 提前返回，`?? "#000000"` 兜住了剩下的部分 —— 所以一个**掩盖**了 ref 缺失的兜底，本身就是缺陷的一部分。jsdom 不会把 `color` 解析进 `getComputedStyle`，因此继承分支只能在浏览器里观察；测试锁定的是让它溜过去的那条契约：色块永远不会拿到那个字面字符串。
+
 - 色块在 effect 里解析，而不是从 ref。ref 在需要它的那次渲染里必然为 null，所以第一版总是回落到黑色 —— 一个为一群并非黑色的点报告黑色的色块 —— 而且 `input[type=color]` 会静默忽略非 hex 的值，改为保留上一个陈旧颜色。现在有一条测试断言色块拿到的永远是它能渲染的形式。
 
 - **点的颜色现在可选择，并且会被复制。** sticky 面板里、紧挨着它所染色的场有一个拾色器 —— 原生色块（带系统取色面板和吸管）、文本框，以及 HEX / RGB / HSL 三个 chip。颜色会进入复制片段，而此前不会：`changedOptions` 从不输出 `color`，所以选了颜色再粘贴的人拿到的是一个用 `currentColor` 绘制的组件，且没有任何提示为什么。
