弹弓玩具 · dsh slingshot toy 🪀

A playful, purely-visual toy for the dsh web GUI. A wooden slingshot lives in the bottom-right corner of the page (drag it anywhere!):

1. 拖拽瞄准 — press and hold the leather pouch, drag it backwards (Angry-Birds style). A dotted arc previews where the stone will fly.
2. 松手发射 — release to fire the stone.
3. 打碎元素 — the stone shatters the first UI element it hits: the element is cloned into shards that burst apart, and the whole wreckage tumbles off the screen under gravity.
4. 自动恢复 — once it has fallen out of the viewport, the original element pops back with a small animation. Nothing in the GUI is ever permanently damaged — html/body and the toy itself are never targeted, and the layout is preserved the whole time (the original is only visibility:hidden while its clone flies).

Extra features:

• 🪵 手柄拖动 — the slingshot has a leather grip handle at the bottom of the trunk (orange-brown, with grip ridges and a grab cursor). Press and drag it to move the slingshot anywhere on the screen (clamped to the viewport) — no mode toggles. The position is persisted in localStorage and restored after reload; the collapsed launcher button follows the gun.
• 🔊/🔇 sound toggle — WebAudio-synthesized boings, crashes and pops (no assets), muted and state persisted in localStorage.
• 💥 score counter (persisted).
• Collapsible widget: ✕ hides it into a small launcher button that pulses and shows a "where did it go" tip.
• The client bundle is part of the dsh client HMR chain: edit lib/client.js and the running page hot-swaps the plugin without a refresh.

安装（给使用者）

DSH 0811 起不再有官方 repository 插件机制，客户端插件统一挂进 web profile：

1. 把本包放进 profile 的模块解析路径（二选一）：

   • 直接把 dsh-client-ui-slingshot 目录复制/软链到 ~/.dsh/profiles/node_modules/@t7kai/ 下，或
   • 用 plugin-registry 控制台 git 源安装： dsh plugin --profile web add "github:/dsh-client-ui-slingshot#main"

2. 在 ~/.dsh/profiles/web/cordis.patch.yml 注册一行（配置层 HMR 热生效，无需重启）：

   - insert:
       - id: ui-slingshot
         name: '@t7kai/dsh-client-ui-slingshot'
