 * TinyHtmlWeekInput is a helper class for managing `<input type="week">` elements.
 * It provides getters and setters for all standard attributes, ensuring type safety
 * and validation for each property.
 *
 * @example
 * const weekInput = new TinyHtmlWeekInput({
 *   value: '2023-W15',
 *   min: '2023-W01',
 *   max: '2023-W52',
 *   step: 1,
 *   required: true
 * });
