/**
 * CTT IbanInput Component
 *
 * A specialized input component for IBAN (International Bank Account Number) validation with auto-formatting.
 * Validates IBANs for all SEPA countries and provides real-time validation feedback.
 *
 * **Features:**
 * - Auto-formatting input mask: displays spaces every 4 characters (e.g., PT50 0002 0123...)
 * - Real-time validation for 36+ SEPA countries
 * - Optional country-specific validation
 * - Mod-97 check digit verification
 * - Stores clean, unformatted values for database/API submission
 *
 * **Input Mask Example:**
 * - Display: `PT50 0002 0123 1234 5678 9015 4` (formatted for readability)
 * - Value: `PT50000201231234567890154` (clean for storage/validation)
 *
 * @slot - Default slot for component content
 *
 * @fires input - Emitted when the input value changes
 * @fires change - Emitted when the input loses focus
 * @fires focus - Emitted when the input receives focus
 * @fires blur - Emitted when the input loses focus
 *
 * @example
 * ```html
 * <!-- Basic usage (all SEPA countries) -->
 * <ctt-iban-input
 *   label="IBAN"
 *   placeholder="Enter your IBAN"
 *   required
 * ></ctt-iban-input>
 *
 * <!-- Country-specific validation -->
 * <ctt-iban-input
 *   country="PT"
 *   label="Portuguese IBAN"
 *   required
 * ></ctt-iban-input>
 * ```
