/**
 * Customize default theme styling by overriding CSS variables:

 */

/**
 * Colors
 *
 * Each colors have exact same color scale system with 3 levels of solid
 * colors with different brightness, and 1 soft color.
 *
 * - `XXX-1`: The most solid color used mainly for colored text. It must
 *   satisfy the contrast ratio against when used on top of `XXX-soft`.
 *
 * - `XXX-2`: The color used mainly for hover state of the button.
 *
 * - `XXX-3`: The color for solid background, such as bg color of the button.
 *   It must satisfy the contrast ratio with pure white (#ffffff) text on
 *   top of it.
 *
 * - `XXX-soft`: The color used for subtle background such as custom container
 *   or badges. It must satisfy the contrast ratio when putting `XXX-1` colors
 *   on top of it.
 *
 *   The soft color must be semi transparent alpha channel. This is crucial
 *   because it allows adding multiple "soft" colors on top of each other
 *   to create a accent, such as when having inline code block inside
 *   custom containers.
 *
 * - `default`: The color used purely for subtle indication without any
 *   special meanings attched to it such as bg color for menu hover state.
 *
 * - `brand`: Used for primary brand colors, such as link text, button with
 *   brand theme, etc.
 *
 * - `tip`: Used to indicate useful information. The default theme uses the
 *   brand color for this by default.
 *
 * - `warning`: Used to indicate warning to the users. Used in custom
 *   container, badges, etc.
 *
 * - `danger`: Used to show error, or dangerous message to the users. Used
 *   in custom container, badges, etc.
