-//! The mounted CPU renderer and App use the same cosmic-text editor engine, but
-//! Iced's Content is parameterized by renderer and cannot be shared between them.
-//! We hit-test the initial click in the laid-out CPU widget, seed that raw caret
-//! in App, and relay the real subsequent SelectWord/SelectLine and editing actions.
-//! App's own Content is never replaced or cursor-normalized after selection. This
-//! tests the actual controller/content boundary without a window or GPU; native
-//! replay remains the check of the complete production renderer/layout path.

-# Pinned Iced widget patch
-
-Upstream crate: iced_widget 0.14.2, MIT. Its registry VCS record identifies
-`iced-rs/iced` commit `54abf81d13fec06d4d9ac754b03ce2c3313e8a1f`, path `widget`.
-The accompanying LICENSE was obtained from that exact upstream commit:
-https://raw.githubusercontent.com/iced-rs/iced/54abf81d13fec06d4d9ac754b03ce2c3313e8a1f/LICENSE
-SHA-256 `fc9086ba4eba4b77e4c603906362742bc3715ffa2c7810c6074fe7780d3a0398`.
-
-All copied src/assets and Cargo manifests retain their upstream bytes except
-`src/text_editor.rs`, which adds one documented read-only `Content::with_editor`
-callback. Original file SHA-256:
-`cecf8686c90aa92066d55075beba545dfb7dd5a44bad0c1519fcb110a56070e1`.
-The callback borrows the existing renderer editor and releases the borrow when
-the closure returns. It adds no mutable editor access or event behavior.
-
-ARCADIA uses this seam to project source diagnostics onto the actual painted
-editor layout. It must not clone/rebuild Content or move user selection for
-measurement. The isolated Windows CPU experiment verified the exact painted
-editor identity and geometry plus retained Word/Line selection and scroll;
-application integration/native validation are separately required.
-
-UPSTREAM-MANIFEST.json records all files from the local pinned registry source,
-including registry bookkeeping and the upstream crate lockfile not copied here.
-Those omitted files are not package inputs. The workspace root Cargo.lock and
-local patch path identify the resolved dependency; this patched package is not
-the unmodified registry checksum. Keep LICENSE and this provenance in source
-captures and generated dependency notices.
-
-On upgrades compare the pristine upstream module and replay only this accessor.
-Recheck actual editor layout, selection/input continuity and annotation tests.
-Remove this patch if upstream provides equivalent read-only layout access.

-# When uploading crates to the registry Cargo will automatically
-# "normalize" Cargo.toml files for maximal compatibility
-# with all versions of Cargo and also rewrite `path` dependencies
-# to registry (e.g., crates.io) dependencies.
-#
-# If you are reading this file be aware that the original Cargo.toml
-# will likely look very different (and much more reasonable).
-# See Cargo.toml.orig for the original contents.

-//! Keyed widgets can provide hints to ensure continuity.
-//!
-//! # What is continuity?
-//! Continuity is the feeling of persistence of state.
-//!
-//! In a graphical user interface, users expect widgets to have a
-//! certain degree of continuous state. For instance, a text input
-//! that is focused should stay focused even if the widget tree
-//! changes slightly.
-//!
-//! Continuity is tricky in `iced` and the Elm Architecture because
-//! the whole widget tree is rebuilt during every `view` call. This is
-//! very convenient from a developer perspective because you can build
-//! extremely dynamic interfaces without worrying about changing state.
-//!
-//! However, the tradeoff is that determining what changed becomes hard
-//! for `iced`. If you have a list of things, adding an element at the
-//! top may cause a loss of continuity on every element on the list!
-//!
-//! # How can we keep continuity?
-//! The good news is that user interfaces generally have a static widget
-//! structure. This structure can be relied on to ensure some degree of
-//! continuity. `iced` already does this.
-//!
-//! However, sometimes you have a certain part of your interface that is
-//! quite dynamic. For instance, a list of things where items may be added
-//! or removed at any place.
-//!
-//! There are different ways to mitigate this during the reconciliation
-//! stage, but they involve comparing trees at certain depths and
-//! backtracking... Quite computationally expensive.
-//!
-//! One approach that is cheaper consists in letting the user provide some hints
-//! about the identities of the different widgets so that they can be compared
-//! directly without going deeper.
-//!
-//! The widgets in this module will all ask for a "hint" of some sort. In order
-//! to help them keep continuity, you need to make sure the hint stays the same
-//! for the same items in your user interface between `view` calls.

-/// A reusable, custom widget that uses The Elm Architecture.
-///
-/// A [`Component`] allows you to implement custom widgets as if they were
-/// `iced` applications with encapsulated state.
-///
-/// In other words, a [`Component`] allows you to turn `iced` applications into
-/// custom widgets and embed them without cumbersome wiring.
-///
-/// A [`Component`] produces widgets that may fire an [`Event`](Component::Event)
-/// and update the internal state of the [`Component`].
-///
-/// Additionally, a [`Component`] is capable of producing a `Message` to notify
-/// the parent application of any relevant interactions.
-///
-/// # State
-/// A component can store its state in one of two ways: either as data within the
-/// implementor of the trait, or in a type [`State`][Component::State] that is managed
-/// by the runtime and provided to the trait methods. These two approaches are not
-/// mutually exclusive and have opposite pros and cons.
-///
-/// For instance, if a piece of state is needed by multiple components that reside
-/// in different branches of the tree, then it's more convenient to let a common
-/// ancestor store it and pass it down.
-///
-/// On the other hand, if a piece of state is only needed by the component itself,
-/// you can store it as part of its internal [`State`][Component::State].
