Layout style properties are stored using indirect values, rather than direct CSS properties.
Allow users without the `unfiltered_html` capability to modify global styles using the indirect block spacing properties `contentSize`, `wideSize`, and `blockGap`, using a mapping of the eventual CSS property to the indirect property stored in `theme.json`. The mapped CSS property is then used for CSS validation.

In the Gutenberg plugin, a position block support feature was introduced last year, that allows a Group block to be set to a "sticky" position, meaning that when the page scrolls, the block will stick to the top of the window.
This change merges the "sticky" position feature for blocks introduced in Gutenberg 15.0.

This changeset introduces functions `wp_get_global_styles_custom_css()` and `wp_enqueue_global_styles_custom_css()`, which allow accessing and enqueuing custom CSS added via global styles.
Custom CSS via global styles is handled separately from custom CSS via the Customizer. If a site uses both features, the custom CSS from both sources will be loaded. The global styles custom CSS is then loaded after the Customizer custom CSS, so if there are any conflicts between the rules, the global styles take precedence.
Similarly to e.g. [55185], the result is cached in a non-persistent cache, except when `WP_DEBUG` is on to avoid interrupting the theme developer's workflow.

This changeset adds the new dimension feature's PHP code for supporting minimum height in the block editor inspector and in global styles. Minimum height is quite useful for defining the minimum vertical dimensions of a block, while allowing it to expand beyond that size.
In this changeset:
* Adds support in `theme.json`.
* Adds support in the style engine.
* Adds support in `wp_apply_dimensions_support()`.
* Renames the setting from `'__experimentalDimensions'` to `dimensions` in `wp_register_dimensions_support()`.
* Adds PHPUnit tests.
Is renaming `'__experimentalDimensions'` a backwards-compatibility (BC) break?
Though the setting has been in the code since 5.9.0, it was never wired to anything, ie it did not expose any controls or styles. Notice in `wp_register_dimensions_support()` and `wp_apply_dimensions_support()` prior to this changeset, there are inline comments as placeholders for height and width support, but no code.
If a developer opted in to use it, it had no effect.
A search in wp.org's plugin and themes repo showed no instances of this experimental setting.
Given there was no functionality attached to it (until this changeset), no change in behavior or effect from removing it, and no usage found in the plugins and themes repository, it does appear to be a BC break.

This changeset results in roughly 4% faster `wp_head` execution time for both block themes and classic themes.

Here's what it does:
* Do not load and parse `theme-i18n.json` schema if the theme does not have a `theme.json` file.
* Fix the variable caching layer around the theme's `theme.json` parsing so that a parent's theme `theme.json` is cached as well.
* Do not run a `WP_Query` for global styles for a user when the theme does not have a `theme.json`.
In a basic WordPress setup, this changeset improves `wp_head` execution time for classic themes by 10%, and overall response time for both block themes and classic themes by 4%. This may seem like a small win, but 4% reduced overall response time is actually quite a bit for one change, and it is worth mentioning that this is just one of several other little performance tweaks which are being worked on to improve performance of `theme.json` parsing further.

Re-order the link pseudo classes to follow the long term LoVe (F)HA rule when set via `theme.json`.
In order that the CSS cascade behaves in a predictable manner, it's recommended that the selectors follow the order `:visited`, `:focus`/`:hover`, `:active`. As order affects the specificity, this ensures the interaction states override the visited states. CSS specificity is really quite beautiful, although complex.

This changeset updates the blocks origin name from core to blocks and adds it to the list of valid origins for `theme.json`.
(See the original fix in [https://github.com//pull/3319 Gutenberg's PR 44363]).
Why?
- This new origin was missing from the list.
- The `core` name is not reflective of what it does, as this data origin is related to block styles, whether they come with WordPress or third-party blocks.
- The existing filter for this piece of data is called `theme_json_blocks`, to reflect it filters "block" data.
- Though `core` origin was used in the past for `default`, this commit reverts it. Why? It was confusing. The goal is to use names that communicate what part of the pipeline are processing (`default > blocks > theme > custom`).
How?
- Renames the string, from `core` to `blocks`.
- Adds `blocks` to the list of valid origins.
- Verifies that the `$theme_json->get_stylesheet()` call uses the proper `$origins` at all times.

When loading a page on the frontend using Xdebug & Webgrind, with the Twenty Twenty-Three theme and no plugins activated, the biggest performance bottleneck currently (on the PHP side) is `WP_Theme_JSON::merge()`. Analysing the data a bit more, it became evident that `WP_Theme_JSON::get_default_slugs()` is the part of that method which takes most of the resources and time.
Further analysis of the method revealed that `array_map()` was the call that slowed it down.
This commit replaces the `array_map()` call with a simple `foreach` loop, improving page load speed significantly.

This commit aims to fix errors caused by incorrect usage of the `strncmp()` function inside the `WP_Theme_JSON::get_property_value()` method on PHP 8.1 and above.
Some history of the affected code:
* [50973] introduced the `WP_Theme_JSON::get_property_value()` method.
* [54162] removed the `$default` parameter from the `_wp_array_get()` call in the method.
With the latter change, the default value that is returned if the path does not exist within the array, or if `$array` or `$path` are not arrays, became `null` instead of an empty string. Since `null` would then be unintentionally passed to the `strncmp()` function further in the code, this caused ~35 errors in the test suite along the lines of:
{{{

}}}
This commit includes:
* Restoring the `$default` value for `_wp_array_get()` call.
* Adding an early return if the value is an empty string or `null`.
* Adding a dedicated unit test to ensure that the method returns a string for invalid paths or `null` values.

This commit introduces fluid typography block supports and switches to use the Style Engine for typography and colors.
The motivation for fluid typography block supports:
>"Fluid typography" describes how a site's font sizes adapt to every change in screen size, for example, growing larger as the viewport width increases, or smaller as it decreases.
>
>Font sizes can smoothly scale between minimum and maximum viewport widths.
Typography changes introduced from Gutenberg:
* Uses the Style Engine to generate the CSS and classnames in `wp_apply_typography_support()`.
* Introduces `wp_typography_get_preset_inline_style_value()` for backwards-compatibility.
* Introduces a private internal function called `wp_get_typography_value_and_unit()`, for checking and getting typography unit and value.
* Introduces a private internal function called `wp_get_computed_fluid_typography_value()`, for an internal implementation of CSS `clamp()`.
* Deprecates `wp_typography_get_css_variable_inline_style()`.

Dynamic (non-explicitly declared) properties are deprecated as of PHP 8.2 and are expected to become a fatal error in PHP 9.0.
There are a number of ways to mitigate this:
* If it is an accidental typo for a declared property: fix the typo.
* For known properties: declare them on the class.
* For unknown properties: add the magic `__get()`, `__set()`, et al. methods to the class or let the class extend `stdClass` which has highly optimized versions of these magic methods built in.
* For unknown ''use'' of dynamic properties, the `#[AllowDynamicProperties]` attribute can be added to the class. The attribute will automatically be inherited by child classes.
Trac ticket #56034 is open to investigate and handle the third and fourth type of situations, however it has become clear this will need more time and will not be ready in time for WP 6.1.
To reduce “noise” in the meantime, both in the error logs of WP users moving onto PHP 8.2, in the test run logs of WP itself, in test runs of plugins and themes, as well as to prevent duplicate tickets from being opened for the same issue, this commit adds the `#[AllowDynamicProperties]` attribute to all “parent” classes in WP.
The logic used for this commit is as follows:
* If a class already has the attribute: no action needed.
* If a class does not `extend`: add the attribute.
* If a class does `extend`:
- If it extends `stdClass`: no action needed (as `stdClass` supports dynamic properties).
- If it extends a PHP native class: add the attribute.
- If it extends a class from one of WP's external dependencies: add the attribute.
* In all other cases: no action — the attribute should not be needed as child classes inherit from the parent.
Whether or not a class contains magic methods has not been taken into account, as a review of the currently existing magic methods has shown that those are generally not sturdy enough and often even set dynamic properties (which they should not). See the [https://www.youtube.com/watch?v=vDZWepDQQVE live stream from August 16, 2022] for more details.
This commit only affects classes in the `src` directory of WordPress core.
* Tests should not get this attribute, but should be fixed to not use dynamic properties instead. Patches for this are already being committed under ticket #56033.
* While a number bundled themes (2014, 2019, 2020, 2021) contain classes, they are not a part of this commit and may be updated separately.
