将滑杆的实际值写入 PERSIST。
如果存档中的值超出 0–100，浏览器会将 el.value 限制在滑杆范围内，但这里又把原始值写入 PERSIST。例如，恢复 blur: 150 后，滑杆显示 100，而下次写盘仍保存 150。请改用 Number(el.value)，使持久状态与滑杆一致。(html.spec.whatwg.org)

避免首次 watcher tick 覆盖刚修改的滑杆。
如果启动时 applyAll(c) 已读到主题，state.lastThemeFp 仍为空。首次 tick 因此再次调用 applyAll(c)，并从 STATE_FILE 恢复旧值。用户若在这两次调用之间调整滑杆，第二次恢复会覆盖该调整。请记录启动时已应用的主题；仅在启动时未读到主题，或主题随后发生变化时重新应用。

…oads late 守护启动那一刻页面 <html> 往往还没挂上主题类（class=""），applyAll 于是整轮 跳过透明契约（日志原文：「读不出主题 → 本轮只注入 UI，不上透明契约」）。 契约样式表一旦缺失，界面全程实心——壁纸其实已经应用成功（记忆恢复 ✓、 舞台有媒体、data-bc-media=video、导入日志「已回填并触发导入」），但用户 看不到任何变化，表现成「自定义背景导入没反应」+「皮肤中心换了也没反应」。 更糟的是这次跳过无法自愈：watcher 的主题重扫条件写作 `state.lastThemeFp && fpTheme !== state.lastThemeFp`，要求上一轮指纹非空， 而启动期恰好是 `'' → 'dark cb-dark vscode-dark'`——这一次变化被前置条件吞掉， 契约再也不会补上（本次实测：注入清单里没有 beauticode-contract-style）。 修复（两处，均只影响启动期时序）： 1. applyAll：主题读不出时按 400ms 重试至多 6 次再放弃——启动竞态通常在 一次重试内即可读到（日志会打「主题延迟可读（第 N 次重试）」）。 2. watcher：去掉 `state.lastThemeFp &&` 前置判断，首个可读主题即触发重扫， 作为即使 applyAll 仍读不到时的兜底自愈。重扫是幂等的。 实测（重启守护）： - 日志：`主题（可用/切换 首次可读）→ 重扫注入 fp=dark cb-dark vscode-dark` 紧接 `contract CSS ✓（beauticode-contract-style）` - 页面：注入清单新增 beauticode-contract-style(3KB) - 画面：截图可见壁纸（用户导入的视频）透过半透明界面显示，修复前为全实心
… is not lost 状态记忆的播种缺陷：`__bcRestoreState` 遵循「值相同就不派发事件」（本意是 不给拖动中的滑杆添乱），于是当存档值恰好等于滑杆默认值时（磨砂 0%、 阴影/透明度同理），既不派发 input 事件、也不写 PERSIST —— 该字段停在 null，下一次写盘把 null 落进 state.json；此后 `st.blur != null` 永假， 这个设置再也恢复不了。 实测痕迹：state.json 出现 `"blur":null`，而界面显示 0%、日志打 `记忆恢复 ✓（… 磨砂=null%）`。 修复：把两件事解耦——「是否派发事件」按值是否变化决定，**状态播种无条件执行** （统一走 restoreSlider(sel,key) 辅助函数，顺带消除三段重复代码）。 回归验证（正是触发条件：把磨砂拖到 0，即等于默认值）： ① 设 0 → state.json blur:0 ② 整页刷新 → 页面 PERSIST blur:0 ③ 刷新后 state.json blur:0（修复前此步退化为 null）✓
…e sink
WorkBuddy 5.6.2 moved its theme token declarations from html down to body
(body[data-vscode-theme-name="…"], body.dark, plain body). Custom properties
resolve to the NEAREST declaration, so our html-level translucent overlay lost
for the whole body subtree no matter how important it was — measured flip point
exactly at the BODY→HTML boundary:
--cb-sidebar-bg html: color-mix(#252526 45%) body: #1f1f1f (opaque)
--wb-bg-primary html: color-mix(#1f1f1f 45%) body: #1f1f1f (opaque)
User-visible effect: sidebar folder headers (._header_99010_11 →
var(--cb-sidebar-bg)) and other var()-painted surfaces rendered opaque while
the panel shell stayed translucent.
Three changes, all keyed to the html theme classes the adapter already uses:
1. Token overlay mirrors both blocks at body scope:
light : html:not(.dark):not(.cb-dark) body (0,2,2)
dark : html.dark body / html.cb-dark body (0,1,2)
both > the host's body-level scopes (0,1,1) and mutually exclusive, so a
theme switch still picks the right block.
2. Both page-side scans now walk nested rules (@layer/@media/@supports and
nested style rules) — a top-level walk missed whole families on 5.6.2.
3. The hardcoded sweep reads backgrounds from rule.style.cssText instead of
getPropertyValue: "background: var(--x)" serialises to "" through the
property API on 5.6.2, which hid surfaces from neutralisation.
Token exclusion refined: *-button-secondary-bg joins the overlay (neutral
surface, measured #262626 opaque on wb-button--secondary); brand/primary
button colours stay excluded on purpose.
Verified on the live host (5.6.2, CDP read-only): body-level
--cb-sidebar-bg / --wb-button-secondary-bg / --wb-bg-primary all compute to
color-mix(… 45%, transparent); ._header_99010_11 computes translucent
(color(srgb … / 0.45)); overlay covers 849 tokens (+3). WorkBuddy suite
39/39; full monorepo suite green (core 39, codex 42, dsh 95, workbuddy 39).

递归扫描时保留 CSS 条件规则。 两个扫描器都会读取 @media 或 @supports 中的规则，但生成的覆盖层没有保留外层条件。原条件不成立时，覆盖层仍可能应用这些值。(w3.org)

保留嵌套选择器的父级作用域。
对于 .shell { .card { background: #fff } }，子规则的 selectorText 是 .card，但原规则只匹配 .shell .card。当前扫描结果会使覆盖层作用于页面上所有 .card。请在收集选择器时解析父级样式规则，或保留原生嵌套结构。(drafts.csswg.org)

从 CSSOM 的 backgroundColor 读取有效颜色。
background: #fff url(icon.svg) 会被当前正则提取为完整简写值。该值通过 LITERAL 检查，但 chromaOf 返回 null，所以扫描会跳过该中性表面。当前正则也会在前面的 background 简写处停止，可能忽略后面的 background-color。
这是一个局部的视觉回归。请使用 CSSOM 的 backgroundColor 长属性读取有效背景色。该修复不会移除背景图片。

After the body-scope mirror, a pink-probe (wallpaper hidden, stage painted #ff00aa) still showed three sidebar surfaces opaque: the project cards (beautiCode / FIRA5V5 / robocup), the bottom user row, and the industry-template switcher button. A whole-tree rect hit-test found no opaque painter, and no custom property on those elements resolved to the leaked colour — the colour entered through var() references. Source of the chain: 5.6.2 adds a new token family --sc-* declared on :root[data-sc-color-scheme="dark"] (e.g. --sc-bg-grey_background: #3a3a3a). The include list had no `sc` prefix, so the family was never scanned and stayed opaque wherever the host referenced it. Add `sc` to TOKEN_INCLUDE_PATTERN. Verified live: overlay grows 894 → 914 tokens, --sc-bg-grey_background computes color-mix(45%) at body level, and the pink probe now turns the entire window pink — no opaque surface left in the sidebar.
