AskaEth 5f85891e7e fix(app-iced): M75 —— 截图取证必须能强制「静息」态(光标污染修掉)
StyleSpec.forced 从 Interaction 改成 Option<Interaction>:Some(Enabled) 与 None 语义不同——
前者强制画静息,后者才跟随 button::Status。修前光标恰好停在某个格子上时,gallery 的
enabled 列会被画成 hover(表现为 text 行出现不该有的灰底容器,看着像 Text 按钮自带容器)。

//! 渲染层几何断言:**对着真截图量像素**(M68 的教训:纯函数返回对,图可能是错的)。
//!
//! `buttons::tests` 只能证明「几何结构体里的数字是 40/20/24」——M68 的药丸正是这样:单测全绿、
//! 图上是 88×32(容器被 `center_x(Length::Fill)` 覆盖)。唯一能抓住这类错误的是**真渲染的像素**。
//! CI 没有桌面,所以这里不自己开窗:先用 `--screen=gallery --screenshot` 出真窗截图,本测试读
//! 那张 PNG 量几何、与令牌逐项比对。**没给图就跳过并大声说出来**(不静默通过)。
//!
//! 复现命令(在 worktree 根目录):
//!
//! ```text
//! cargo build -p unlucky-app-iced --bin unlucky-launcher-iced
//! ./target/debug/unlucky-launcher-iced --software-renderer --screen=gallery //! --screenshot target/m75/gallery-light.png --screenshot-theme=light
//! ULL_GALLERY_SHOT=target/m75/gallery-light.png cargo test -p unlucky-app-iced gallery::probe
//! ```
//!
//! 量什么(每条对一个已发生过的错误):实心块高 **40**(12b 1.1)· 药丸顶行宽 ≈9 ⇒ 圆角 full=20
//! (12b 1.2,8 圆角会接近通栏)· IconButton **40×40**(12b 2.1)· 字形墨迹 **16~26**
//! (Q9:24 盒被填满会到 40)· 分隔线 **1px**(22.1)· 禁用容器 **on-surface@12%** 存在(12b 1.8)。
