/**
 * @description
 * Show and Conceal (SNC) component that toggles visibility of sensitive content with masked placeholder.
 * Displays a configurable number of dots to represent hidden content length.
 * Provides a toggle button to reveal or conceal the actual content.
 * Commonly used for passwords, API keys, tokens, or other sensitive information that should be hidden by default.
 * Emits visibility state changes for parent components to track or respond to content exposure.
 *
 * @usageNotes
 * ### Basic Usage
 * ```html
 * <!-- Simple password field -->
 * <eui-snc [dotsLength]="12" (sncToggle)="onToggle($event)">
 *   MySecretPassword123
 * </eui-snc>
 * ```
 *
 * ```typescript
 * onToggle(isVisible: boolean) {
 *   console.log('Content is now:', isVisible ? 'visible' : 'hidden');
 * }
 * ```
 *
 * ### Accessibility
 * - Toggle button should have clear aria-label indicating show/hide action
 * - Announce state changes to screen readers using aria-live regions
 * - Ensure keyboard navigation works for toggle button
 *
 * ### Notes
 * - Default dotsLength is 8 characters
 * - Content is hidden by default on component initialization
 * - Use sncToggle event to track visibility changes for security logging
