I think this is the same work we did here https://phabricator.wikimedia.org/T356677, are we targeting all extensions and skins, ... ?
https://codesearch.wmcloud.org/search/?q=codex-search-styles&files=&excludeFiles=&repos=

the the changes should include:

• In skin.jsonor extension.json under "ResourceModules" add

"name.of.repo.prefix.search.codex.styles": {
	"class": "MediaWiki\\ResourceLoader\\CodexModule",
	"codexStyleOnly": true,
	"codexComponents": [
		"CdxTypeaheadSearch",
		"CdxSearchInput",
		"CdxButton",
		"CdxRadio",
		"CdxMessage"
	]
},
"name.of.repo.prefix.search.codex.scripts": {
	"dependencies": [
		"skins.vector.search.codex.styles"
	],
	"class": "MediaWiki\\ResourceLoader\\CodexModule",
	"codexScriptOnly": true,
	"codexComponents": [
		"CdxTypeaheadSearch"
	]
}

• If the styles are only needed do not add the "name.of.repo.prefix.search.codex.scripts"
• Make sure name.of.repo.prefix.search.codex.scripts and/or name.of.repo.prefix.search.codex.styles modules is loaded and available to use. depending on the area you can use mw.loader.load/mw.loader.using, skin.json required module, $out->addModuleStyles, and $out->addModuleScript
