/**
 * Set or get HTML attributes on one or more elements.
 *
 * Provides a unified interface for attribute manipulation,
 * mirroring the `css()` pattern with `.remove()` and `.has()` methods.
 *
 * @example
 *     attr(el, { 'data-id': '123', role: 'button' });
 *     attr(el, 'role');                // → 'button'
 *     attr(el, ['role', 'data-id']);    // → { role: 'button', 'data-id': '123' }
 *     attr.remove(el, 'role');
 *     attr.has(el, 'disabled');        // → boolean
