//! CDP prompt + clipboard helpers on `App` — the `add/edit/delete`
//! prompts and accept-handlers for LocalStorage / SessionStorage /
//! IndexedDB / Cookies rows, DOM-selector copy, screenshot + PDF
//! save-to-disk, and Request-pane response-body copy. The heavy
//! lifting (CDP protocol, keychain) lives in `cdp.rs`; this file
//! is the App-method surface.
//!
//! Extracted from `app/mod.rs` (file-split refactor — Task #963).
//! Pure non-destructive move; no API change.
