// This file is the central place where we declare
// which variables are part of the "mediawiki.skin.variables.less"
// API that core and extensions can use in their style modules.
// This includes all of the Codex design tokens, as well as some additional variables.
//
// The initial values are intended merely as fallback to allow
// forward and backward compatibility to allow new variables
// to be defined without breaking existing implementations by
// skins.
//
// @since 1.36
// Add `@since` line above every added variable (block) per MediaWiki version.
//
// == Instructions for skins ==
//
// In skin.json, add:
//    "SkinLessImportPaths": {
//        "skinname": "resources/mediawiki.less"
//    }
//
// Create a file called resources/mediawiki.less/mediawiki.skin.variables.less, which starts with:
//    @import 'mediawiki.skin.default.less';
// then import the Codex theme for this skin, e.g.:
//    @import 'mediawiki.skin.codex-design-tokens/theme-wikimedia-ui.less';
// followed by any overrides for these variables, e.g.:
//    @min-width-breakpoint-desktop: 1234px;

// Make all Codex mixins available when mediawiki.skin.variables.less is imported
@import 'mediawiki.skin.codex/mixins/codex-public-mixins.less';

// Skin variables that are not Codex tokens:

// Form input labels for buttons, dropdowns, but also text input values.
// Note that there are binary inputs in skins like Vector, that receive a different treatment
// with name `*-input-binary`.

// ----- Neutral values for Codex tokens: -----
// @since 1.41
// We don't import any of the existing Codex themes here. Instead, we provide neutral, unbranded
// values for every Codex token. Skins can override these individually, or they can override them
// en masse by importing a Codex theme. In the future, these values should be migrated into
// Codex as its base theme, once Codex has a proper theming system that allows for this (T296689).
