MyGo v0.5.5 returns ui.Element as a checked value handle instead of a
pointer. Migrated with `mygo migrate-ui`, then fixed what the codemod
leaves to review:
- Element nil checks become .Valid(); absent elements are ui.Element{}.
- Input handlers and paint callbacks run outside the build pass, where
elements expire and Context methods are inert: read IsDisabled into a
local during the build, keep a ui.Handle for Focus, use c.Services()
for clipboard access, create ui.Local state during the build.
- Add core.AutoFocus: v0.5.5 records an overlay's opener after its
content builds, so same-frame autofocus lost focus restore on close.
It focuses one frame later; cascader rows defer their focus likewise.
- core.OverlayLayer identifies build passes by the root element, not
c.Now(), which repeats across passes and under the Tester clock.
- Context menus survive the opening press counted as PressedOutside;
split button tooltip no longer reorders its open menu; disabled
menubar rows pass presses to the panel; Form defers blur-started
async checks so the growing message no longer moves Submit away
from the release; Combobox drops its disabled copy now that MyGo
blocks typing under a disabled wrapper (canary flipped to a guard).
- The Tester clock is virtual: tests use Advance/Now instead of
time.Sleep/time.Now and read element state inside the view. The web
mirror advances the clock to wall time before each frame and input.
- AGENTS.md and docs describe the value Element API and the new pin.
Snapshot goldens are darwin-only and were not re-verified here.

MujicaUI
宫廷哥特风格的 Go 桌面组件库，建立在 MyGo 原生 UI 之上。象牙白与炭黑底色，酒红主色，旧金装饰线，衬线标题。100 个组件，浅深两套主题，三种密度。
界面由 MyGo 在 GPU 上自绘，不使用 HTML、JavaScript 或 WebView。
安装
go get git.zacharyzhang.com/ZacharyZhang-NY/MujicaUI
要求 Go 1.27.1 与 MyGo v0.2.10（见 兼容表）。
最小示例
即 examples/minimal/main.go，CI 校验两者一致。
package main
import (
"log"
"github.com/egoist/mygo"
"github.com/egoist/mygo/ui"
"git.zacharyzhang.com/ZacharyZhang-NY/MujicaUI/core"
"git.zacharyzhang.com/ZacharyZhang-NY/MujicaUI/input"
)
type app struct{ name string }
func (a *app) view(c *ui.Context) {
core.Use(c, core.Settings{Locale: core.ZhCN})
ui.Column(c).Fill().Center().Gap(12).Children(func() {
input.TextInput(c, &a.name, input.TextInputOptions{Placeholder: "姓名"})
if input.Button(c, "觐见", input.ButtonOptions{}).Clicked() {
log.Println("hello", a.name)
}
})
}
func main() {
a := &app{}
mygo.App.WhenReady(func() {
mygo.NewWindow(mygo.WindowOptions{Title: "Mujica", Width: 480, Height: 320, Content: ui.View(a.view)})
})
if err := mygo.App.Run(); err != nil {
log.Fatal(err)
}
}
主题
每帧开头调用 core.Use(c, settings)。Settings 决定模式（System、Light、Dark）、密度（theme.Compact、theme.Default、theme.Comfortable）、语言与文案覆盖。每个窗口各自设置，切换不重置业务状态。
core.Use(c, core.Settings{
Mode: core.Dark,
Density: theme.Compact,
Locale: core.ZhCN,
})
k := core.Tokens(c) // 当前窗口的颜色
覆盖顺序：组件参数，窗口 Settings，库默认值。系统高对比度、文本缩放、减少动画始终生效。
Gallery
go run ./examples/gallery # 原生窗口
go run ./examples/gallery -web 127.0.0.1:8080 # 浏览器镜像，仅本机
-web 按传入的地址监听；写 :8080 会对所有网络接口开放。浏览器镜像不在浏览器里运行组件。Go 进程用 ui.NewTester 驱动同一个 Gallery 视图，把帧推给页面，再把指针、键盘、输入法和剪贴板事件送回 Go。
