* Custom CSS is associated with a given theme and is displayed in an inline `style` element at the `wp_head` hook after the `wp_print_styles` is called so that it overrides any enqueued stylesheets.
* A `wp_get_custom_css()` function is used for accessing the CSS associated with the current theme (or another theme) and a `wp_get_custom_css` filter for manipulating it.
* CSS is managed in customizer via a new "Additional CSS" section with a single `textarea` control.
* `WP_Customize_Section::$description_hidden` is introduced for hiding extended descriptions in customizer sections behind a help toggle as done with panels.
* CSS is stored in a `custom_css` post type with the theme (stylesheet) slug as the `post_name`.
* `WP_Customize_Custom_CSS_Setting` is introduced to handle validation of CSS, previewing, and persisting the CSS to the `custom_css` post type.
* The `custom_css` setting is tied to a new `unfiltered_css` capability which maps to `unfiltered_html` by default.
* Escaping the message in the notification template is removed to allow markup (`code` tags) to be rendered.

Send back setting validities with full refreshes and selective refreshes so that invalid settings can have notifications displayed immediately before attempting save, and so that these notifications can be cleared as soon as the input is corrected.
* Splits out JS logic for listing controls into separate methods `wp.customize.Setting.prototype.findControls()` and `wp.customize.findControlsForSettings()`.
* Adds a `setting` property to the `data` on notifications added to controls that are synced from their settings.
* Adds `selective-refresh-setting-validities` message sent from preview to pane.
* Changes `WP_Customize_Manager::validate_setting_values()` to return when settings are valid as well as invalid.
* Adds `WP_Customize_Manager::prepare_setting_validity_for_js()`.
* Add setting validities to data exported to JS in Customizer Preview and in selective refresh responses.

Eliminates JS logic (from [36698]) which attempted to do pure JS update while waiting for the selective refresh response to return. The duplicate JS logic lacked a re-implementation of the `image_downsize()` functionality available in PHP, and so the JS preview logic would fail to properly preview images that didn't have the exact theme image size generated. To keep the code DRY and to eliminate the momentary display of an improperly-sized image, the duplicated JS logic is now removed.

* Removes double `margin-bottom` from all the media controls.
* All media controls now send `{settingId}-attachment-data` messages to the preview when a media setting is updated so that the preview has access to the attachment data.
* Fixes receiving of `attachment-data` message for `custom_logo` which resulted in instant JS-applied preview not working. See #36096.

* Introduce `WP_Customize_Manager::get_nonces()` to consolidate logic for retrieving nonces.
* Export nonces centrally in `wp.customize.settings.nonce` with each request and update nav menus preview to utilize.
* Send updated nonces to preview upon `nonce-refresh`.
* Request full preview refresh if Nav Menu selective refresh request fails (e.g. due to bad nonce).
* Update nav menus and widgets in Customizer to utilize `customize_refresh_nonces` for exporting nonces and keeping them up to date.

* Ensure that Setting `Value` objects in preview get initial `_dirty` flag set if values among POST data.
* Upon `saved` event, send `saved` message to preview with the `response` to trigger `saved` event there.
* Reset `_dirty` flag for all setting `Value` objects in preview upon `saved`.
* Continue to create settings synced from pane even after initial bootstrap, and create them as dirty.
* Ensure that `id` property is set for setting `Value` objects in preview.

* Prevent following jump links (starting with `#`), but instead scroll that element into view.
* Prevent following links clicked in the Customizer if shift key is pressed when clicking; this fixes an issue when trying to shift-click on a widget or nav menu item (#32681) to just focus on the control in the Customizer.

Control can indicate its active state by a subclass overriding the 'active_callback' method, by supplying a callable 'active_callback' argument into the control's constructor, or by filtering 'customize_control_active'.

* This moves our "development" versions from .dev.js to .js (same for css).
* The compressed version then moves from .js to .min.js (same for css).
By switching to the standard .min convention, it sets expectations for developers,
and works nicely with existing tools such as ack.
