+- `src/pages/admin/write.rs` initializes via `src/tiptap_bridge.rs` (wasm-bindgen bindings): injects `Closure` callbacks (`onUpdate`/`onReady`/`onUploadEvent`/`onImageUpload`) into `TiptapEditor.create`, holds the instance + closures in `EditorHandle` (Drop calls `destroy()`). No `js_sys::eval`, no `window` globals, no polling.
