AI disclosure: I asked GitHub Copilot (Claude Haiku 4.5) "What's the best way to add tests for my recently merged qt theming contributions?" It suggested the insta crate for golden testing the output strings as well as some unit tests. I implemented it myself.
This way, the test log can show the expected and actual result if it fails.

We're now merging the colors with kdeglobals, not replacing it with a symlink. So renaming the file gives us a missing file Io error:
[2026-02-18T20:03:08Z ERROR cosmic_settings_daemon::theme] Failed to apply COSMIC theme exports. Io(Os { code: 2, kind: NotFound, message: "No such file or directory" })
This also changes `widget::column::with_children` and
`widget::row::with_children` to take an `impl IntoIterator` instead
of a `Vec`, like the `iced` variants of these functions do.
This shouldn't be a breaking change since passing in a `Vec` will still
compile and function exactly as before.
(Using `iced::widget::Column::from_vec` or
`iced::widget::Row::from_vec` isn't possible, since the elements of the
`Vec` aren't checked, so the size of the resulting `Column` or `Row`
won't adapt to the size of its children. Perhaps a new function could
be added to mirror `iced`'s?)
To reduce compile-times and avoid some overhead to binary size, this will modify some of our
generic functions to use non-generic inner functions where possible. The inner functions are
marked carefully with `#[inline(never)]` to prevent being inlined by LLVM at their callsites
While looking for generic functions to optimize, I have also taken the opportunity to annotate
public non-generic getters and setters with `#[inline]` to ensure that LLVM will inline them
across crate boundaries. By default, only generic functions are automatically inlined, and
only when enabling fat LTO are constant functions reliably inlined across crate boundaries.
Increases Compact header height to 40 (from 36), to better accommodate larger widgets (e.g. the search bar). This makes it distinct from the SSD header, which is now addressed by the `_` match case.
Also makes the horizontal header padding fixed at 8, so that the app window padding can also be 8.
