 *
 * @example Default
 * ```html
 * <sigvelo-text-area name="feedback" label="Feedback"></sigvelo-text-area>
 * ```
 *
 * @example Labels and descriptions
 * You can use the `label` and `description` attributes to provide plain text labels and descriptions for the text area. If you want to provide HTML, use the `label` and `description` slots instead.
 *
 * ```html
 * <sigvelo-text-area name="feedback" label="Feedback">
 *   <span slot="description">
 *     For more information, <a href="https://example.com/" target="_blank">visit our website</a>.
 *   </span>
 * </sigvelo-text-area>
 * ```
 *
 * @example Providing an initial value
 * Use the `value` attribute to provide an initial value for the text area.
 *
 * ```html
 * <sigvelo-text-area name="feedback" label="Feedback" value="This is the greatest and best song in the world."></sigvelo-text-area>
 * ```
 *
 * @example Adding a placeholder
 * Use the `placeholder` attribute to show a placeholder in the text area when it's empty.
 *
 * ```html
 * <sigvelo-text-area
 *   name="bio"
 *   label="Biography"
 *   placeholder="Tell us about yourself"
 * ></sigvelo-text-area>
 * ```
 *
 * @example Changing the number of rows
 * Use the `rows` attribute to set the default number of text rows.
 *
 * ```html
 * <sigvelo-text-area label="One row" rows="1"></sigvelo-text-area><br>
 * <sigvelo-text-area label="Five rows" rows="5"></sigvelo-text-area>
 * ```
 *
 * @example Resizing to fit content
 * Text areas can grow with their content by setting the `resize` property to `auto`. The minimum number of rows shown is determine by the `rows` attribute.
 *
 * ```html
 * <sigvelo-text-area label="Resizing to fit" resize="auto" rows="4"></sigvelo-text-area>
 * ```
 *
 * @example Filled and unstyled text areas
 * Set the `variant` attribute to `normal`, `filled`, or `unstyled` to change the text area's variant.
 *
 * ```html
 * <sigvelo-text-area variant="normal" label="Normal text field" placeholder="Enter some text"></sigvelo-text-area><br>
 * <sigvelo-text-area variant="filled" label="Filled" placeholder="Enter some text"></sigvelo-text-area><br>
 * <sigvelo-text-area variant="unstyled" label="Unstyled" placeholder="Enter some text"></sigvelo-text-area>
 * ```
 *
 * @example Changing the size
 * Use the `size` attribute to change the text area's size.
 *
 * ```html
 * <sigvelo-text-area size="xs" label="Extra small"></sigvelo-text-area><br>
 * <sigvelo-text-area size="sm" label="Small"></sigvelo-text-area><br>
 * <sigvelo-text-area size="md" label="Medium"></sigvelo-text-area><br>
 * <sigvelo-text-area size="lg" label="Large"></sigvelo-text-area><br>
 * <sigvelo-text-area size="xl" label="Extra large"></sigvelo-text-area>
 * ```
 *
 * @example Disabling
 * Use the `disabled` attribute to disable the text area.
 *
 * ```html
 * <sigvelo-text-area label="Disabled" disabled></sigvelo-text-area>
 * ```
 *
 * @example Showing labels on the side
 * With the `sigvelo-side-label` utility, you can show labels on the side instead of on top of the text area. You can control the width of the label by setting the `--label-width` custom property.
 *
 * ```html
 * <sigvelo-text-area
 *   class="sigvelo-side-label"
 *   style="--label-width: 8ch;"
 *   name="name"
 *   label="Feedback"
 *   description="Let us know what you think"
 * ></sigvelo-text-area>
 * ```
 *
 * @example Validation
 * A number of attributes can be used to enable validation using the Constraint Validation API. These include `required`, `minlength`, and `maxlength`. They work exactly like their native counterparts.
 *
 * ```html
 * <form action="about:blank" method="get" target="_blank">
 *   <sigvelo-text-area name="required" label="Required" required></sigvelo-text-area><br>
 *   <sigvelo-text-area name="minlength" label="Minimum length (enter at least five characters)" required minlength="5"></sigvelo-text-area><br>
 *   <sigvelo-text-area name="maxlength" label="Maximum length (enter no more than five characters)" required maxlength="5"></sigvelo-text-area><br>
 *   <sigvelo-button type="submit" color="primary">Submit</sigvelo-button>
 *   <sigvelo-button type="reset">Reset</sigvelo-button>
 * </form>
 * ```
 *
 * @example Using custom validation
 * Use the `setCustomValidity()` method to make the text area invalid and show a custom error message on submit. This will override all other validation parameters. To clear the error, remove the attribute or set it to an empty string.
 *
 * ```html
 * <form action="about:blank" method="get" target="_blank" id="text-area__custom-validation">
 *   <sigvelo-text-area
 *     name="feedback"
 *     label="Feedback"
 *     description="This field will be invalid until custom validation is removed"
 *   ></sigvelo-text-area>
 *   <br>
 *   <sigvelo-button type="submit" color="primary">Submit</sigvelo-button>
 * </form>
 *
 * <script type="module">
 *   import { allDefined } from '/dist/sigvelo.js';
 *
 *   await allDefined();
 *
 *   const form = document.getElementById('text-area__custom-validation');
 *   const textArea = form.querySelector('sigvelo-text-area');
 *
 *   textArea.setCustomValidity('Not so fast, bubba!');
 * </script>
 * ```
 *
 * @example Styling validation
 * You can style valid and invalid text area using the `:valid` and `:invalid` pseudo classes.
 *
 * ```html
 * <form action="about:blank" method="get" target="_blank" class="text-area__validation-pseudo">
 *   <sigvelo-text-area
 *     name="feedback"
 *     label="Feedback"
 *     description="This field is required"
 *     required
 *   ></sigvelo-text-area>
 *   <br>
 *   <sigvelo-button type="submit" color="primary">Submit</sigvelo-button>
 *   <sigvelo-button type="reset">Reset</sigvelo-button>
 * </form>
 *
 * <style>
 *   .text-area__validation-pseudo {
 *     sigvelo-text-area:valid {
 *       outline: solid 2px var(--sigvelo-color-success-border);
 *       outline-offset: .5rem;
 *     }
 *
 *     sigvelo-text-area:invalid {
 *       outline: solid 2px var(--sigvelo-color-danger-border);
 *       outline-offset: .5rem;
 *     }
 *   }
 * </style>
 * ```
 *
 * However, these selectors will match even before the user has had a chance to fill out the form. More often than not, you'll want to use the `user-valid` and `user-invalid` custom states instead. This way, validation styles are only shown _after_ the user interacts with the form control or when the form is submitted.
 *
 * ```html
 * <form action="about:blank" method="get" target="_blank" class="text-area__validation-custom">
 *   <sigvelo-text-area
 *     name="feedback"
 *     label="Feedback"
 *     description="This field is required"
 *     required
 *   ></sigvelo-text-area>
 *   <br>
 *   <sigvelo-button type="submit" color="primary">Submit</sigvelo-button>
 *   <sigvelo-button type="reset">Reset</sigvelo-button>
 * </form>
 *
 * <style>
 *   .text-area__validation-custom {
 *     sigvelo-text-area:state(user-valid) {
 *       outline: solid 2px var(--sigvelo-color-success-border);
 *       outline-offset: .5rem;
 *     }
 *
 *     sigvelo-text-area:state(user-invalid) {
 *       outline: solid 2px var(--sigvelo-color-danger-border);
 *       outline-offset: .5rem;
 *     }
 *   }
 * </style>
 * ```
