The `{min|max}-device-pixel-ratio` syntax as a a non-standard CSS media feature that was used as an alternative to the now standard `resolution`. Prior to Safari 16.0, `-webkit-{min|max}-device-pixel-ratio` was needed to correctly support it.
This change is a result of the `caniuse-lite` update that was applied recently in [56065]. Though there were no changes to target browsers as a result of this update, it seems an upstream change identified these as unnecessary.

This is part of a larger project in cleaning up core's admin CSS. This collapses all colors used in the CSS to one of 12 blues, greens, reds, and yellows, 13 grays, pure black, and pure white. The colors are perceptually uniform from light to dark, half of each range has a 4.5 or higher contrast against white, the other half has a 4.5 or higher contrast against black.
Standardizing on this set of colors will help contributors make consistent, accessible design decisions. The full color palette can be seen here: https://codepen.io/ryelle/full/WNGVEjw

Patches occasionally come in on generated files. We should be kind to new contributors and give them a hint that these files are auto-generated.
This is a follow-up to [41271], which added the banner to minified CSS files.

In many a strange and curious file of forgotten lore—
While I pondered, blaming Nacin, my notifications suddenly awakened,
As of someone quietly DMing;—DMing me, I can’t ignore.
“’Tis some contributor,” I muttered, “DMing me an idea or four—
Only this and nothing more.”
Ah, distinctly I remember, at WordCamp US, last December;
A mad proposal nearly laid me—down out cold—upon the floor.
Curious, I listened closely;—to a plan I agreed with, mostly—
A way to make our JavaScript—JavaScript which was a chore—
Maintainable, extendable, for the future, is what I saw.
Guten-ready for evermore.
Open here I switch to Slack, when, with many a patch and hack,
In there stepped Omar, a JavaScript developer hardcore;
Pronouncing all the changes fit; ready now to be commit;
“There’s nothing else for us to do,” DMing me, “It’s done!” he swore—
“No longer random guessing at which file need next be explored—
Let’s move on, we’re all aboard.”
Moved all together, grouped and managed, in folders all is packaged,
The code had all been cleaned and tidied, important parts moved to the fore,
“Though this change be useful here,” I said, “it is too large, I fear,
We couldn’t manage such a patch, we’ve done nothing like this before—
Tell me where doth go this change, change to make our codebase soar!”
Quoth Omar, “In WordPress Core.”
Props omarreis for shepherding this significant change.

WordPress no longer supports many old old browsers: https://make.wordpress.org/core/2017/04/23/target-browser-coverage/
This also removes alot of no longer necessary CSS. It served us well, but we are never getting back together with IE8,9,10.
So, in the (paraphrased) words of Taylor Swift:
I remember when we dropped support the first time
Saying, "This is it, I've had enough, " 'cause like
We hadn't seen many users in a month
When you said you needed flexbox. (What?)
Then you postMessage again and say
"IE8, I miss you and I swear I'm gonna change, trust me."
Remember how that lasted for a day?
I say, "I hate the box model, " we break up, you call me, "I love css-grids."
Ooh, we called it off again last night
But ooh, this time I'm telling you, I'm telling you
We are never ever ever supporting IE 8,9,10,
We are never ever ever supporting IE 8,9,10,
You go talk to EDGE, talk to my FIREFOX, talk to CHROME
But we are never ever ever ever getting back together
Like, ever...

After [40059] the CSS class `button-link` uses `text-align: left` by default.
This change now requires to limit as much as possible the use of `button-link`
to controls that should really look like links and to explicitly set
`text-align: center` in a few other cases.

Rejoice, for your admins will feel more native to your surrounding computing environment and likely load faster, especially when offline, as they no longer have to talk to The Google Overlord.
At the time of introduction in 3.8, there were not good system fonts common to all platforms at the time. In the years since, Windows, Android, OS X, iOS, Firefox OS, and various flavors of Linux have all gotten their own (good) system UI fonts.
There will definitely be visual bugs, mainly around alignment and spacing; these should be documented and reported on the ticket and fixed more atomically so that our current and future selves have a better understanding of what happened and why.
The style remains registered, as it is almost certainly in use by themes and plugins.

We'll be using it for two distinct tasks:
* Core CSS files will keep prefixes. `grunt autoprefixer:core` will update files directly in src/ as a pre-commit step, rather than doing it on build.
* Color CSS files will receive prefixes when they are built.
This commit:
* Adds prefixes we were missing to core CSS.
* Removes prefixes that we no longer need from core CSS.
* Removes all prefixes from colors CSS.

RTL files are now created on build for core CSS files. These files replace the LTR file completely, rather than being in addition to the existing LTR file.
Benefits:
* For the user: less CSS is served in RTL, less HTTP requests on the frontend, and less work for the browser.
* For the core developer: Let the tools do the work.
Notes for core development:
* The file generation task is `grunt rtl`.
* `grunt watch` now handles generating RTL files in /build when a CSS file in /src is saved.
* /src is now locked to LTR. RTL testing must occur via /build. When attempting to run an RTL text direction with /src, an admin notice will display.
Expect RTL bugs. Please report them.
