There are several issues with the MDC (Markdown Components) syntax regarding the number of colons used, which will likely cause rendering errors.

1. Components with slots: Components that use named slots (like #headline, #title, etc.) must be wrapped with three colons (:::), not two (::). This applies to PageHero (line 8) and all PageSection components (lines 28, 68, 97). Their closing tags must also be :::.

2. Nested components: When nesting components, each level of nesting should add a colon. The current implementation is inconsistent. Based on Nuxt Content's documentation, if PageSection is ::: (3 colons), a component inside its default slot like the div on line 35 should be :::: (4 colons), and PageCards inside that div (e.g., line 36) should be ::::: (5 colons). Similarly, ButtonA inside PageHero's #links slot should be ::::.

This needs to be corrected throughout the file for the components to render correctly.

By explicitly binding only a few props to NuxtLink, you are losing support for all other NuxtLinkProps that were previously supported with v-bind="props". This is a regression, as props like activeClass or replace will no longer work.

To fix this while still separating the Button props, you can create a computed property that contains only the NuxtLinkProps and then use v-bind on the NuxtLink component.

First, add this to your <script> section:

import { computed } from 'vue'

// ... after props definition

const nuxtLinkProps = computed(() => {
  const { variant, size, ...rest } = props
  return rest
})

Then, you can use it in the template with this suggestion.

    <NuxtLink v-bind="nuxtLinkProps">
      <slot />
    </NuxtLink>

The component is designed to act as a link when the to prop is provided. However, it only accepts to and target props for linking, limiting its capabilities. It would be more flexible if it accepted all NuxtLinkProps, similar to how the ButtonA component is being refactored. This would allow using props like external, rel, activeClass, etc.

You could change the props definition to extend NuxtLinkProps and then separate the props to be passed to NuxtLink.

Example of updated script:

import type { HTMLAttributes } from 'vue'
import type { NuxtLinkProps } from '#app'
import { Card, CardContent, CardDescription, CardHeader, CardTitle } from '~/components/ui/card'

interface Props extends NuxtLinkProps {
  title?: string
  description?: string
  icon?: string
  orientation?: 'vertical' | 'horizontal'
  class?: HTMLAttributes['class']
}

const props = defineProps<Props>()

const isLink = computed(() => !!props.to)

const linkProps = computed(() => {
  // eslint-disable-next-line @typescript-eslint/no-unused-vars
  const { title, description, icon, orientation, class: klass, ...rest } = props
  return rest
})

And in the template, you would bind these props to the NuxtLink component:

<component
  :is="isLink ? 'NuxtLink' : 'div'"
  v-bind="isLink ? linkProps : {}"
  ...
>

This would make the component much more versatile.

The v-if="page" directive is redundant here. The if (!page.value) check on line 9 ensures that page.value is defined. If it's not, an error is thrown, and this part of the component will not be rendered. You can safely remove the v-if for cleaner code.

The horizontal rule syntax ---- (4 dashes) is non-standard. Standard Markdown uses either --- (3 dashes), *** (3 asterisks), or ___ (3 underscores) for horizontal rules. Using 4 dashes may not render correctly in all Markdown parsers.

Using target="_blank" without rel="noopener noreferrer" on external links enables reverse tabnabbing, allowing the opened page to access window.opener and potentially navigate the original tab to a malicious site. An attacker controlling https://github.com/pleaseai/docs (or any external URL opened in a new tab) could exploit this to phish users or hijack the session context. Fix by adding rel="noopener noreferrer" to the link via the ButtonA component or directly in MDC, e.g., :::ButtonA{to="https://..." target="_blank" rel="noopener noreferrer"} or by enforcing rel on all external target="_blank" links inside ButtonA.
