/**
 * @description
 * A versatile button component that supports various states, sizes, and visual styles.
 * It can be used as a native `<button>` or `<a>` element while preserving consistent EUI behavior and styling.
 *
 * @usageNotes
 * #### Basic buttons with variants
 * ```html
 * <button euiButton>Default</button>
 * <button euiButton euiPrimary>Primary</button>
 * <button euiButton euiSecondary>Secondary</button>
 * <button euiButton euiSuccess>Success</button>
 * ```
 *
 * #### Icon button
 * ```html
 * <button euiButton euiIconButton aria-label="Notifications">
 *   <eui-icon-svg icon="bell:outline"></eui-icon-svg>
 * </button>
 * ```
 *
 * #### CTA and block buttons
 * ```html
 * <button euiButton euiCTAButton>Call to Action</button>
 * <button euiButton euiBlockButton>Full Width</button>
 * ```
 *
 * #### Size variants
 * ```html
 * <button euiButton euiSizeS>Small</button>
 * <button euiButton euiSizeM>Medium</button>
 * <button euiButton euiSizeL>Large</button>
 * ```
 *
 * #### Disabled and checked states
 * ```html
 * <button euiButton [euiDisabled]="true">Disabled</button>
 * <button euiButton [isChecked]="true">Checked</button>
 * ```
 *
 * #### As link
 * ```html
 * <a euiButton href="/page">Link Button</a>
 * ```
 *
 * ```ts
 * onButtonClick(button: EuiButtonComponent): void {
 *   console.log('Button clicked:', button);
 * }
 * ```
 *
 * ### Accessibility
 * - Native button/anchor semantics preserved for screen readers
 * - Keyboard accessible with Enter/Space (button) or Enter (link)
 * - euiIconButton requires aria-label for icon-only buttons
 * - Disabled state prevents interaction and is announced to screen readers
 * - Focus ring visible by default (remove with hasNoFocusRing if alternative focus indicator exists)
 * - isChecked state is visually indicated and announced
 *
 * ### Notes
 * - Use on `<button>` or `<a>` elements via euiButton attribute
 * - Color variants: euiPrimary, euiBranding, euiSecondary, euiSuccess, euiInfo, euiWarning, euiDanger, euiInverse
 * - Size variants: euiSizeXS, euiSizeS, euiSizeM (default), euiSizeL
 * - euiBasicButton removes background for minimal styling
 * - euiCTAButton applies prominent call-to-action styling
 * - euiBlockButton makes button full-width
 * - euiIconButton optimizes layout for icon-only content
 * - euiAvatarButton styles for avatar dropdown triggers
 * - euiLineWrap allows multi-line button text
 * - isCompact reduces padding and dimensions
 * - euiOutline applies outline/ghost styling
 * - euiRounded applies rounded corners
 * - euiResponsive adjusts sizing based on viewport
 * - euiStart/euiEnd aligns content within button
 * - buttonClick event emits component instance on click
