## MODIFIED Requirements

### Requirement: Media modal dialog
The site MUST provide a modal dialog that displays embedded media (YouTube video or podcast episode) when a user clicks a video or podcast content card on a listing surface (homepage, `/videos`, `/podcast`).

The modal MUST render the following elements in order:

- A header row with the content title on the left and a close button on the right
- An embedded media player (YouTube iframe for videos; Spotify embed for podcast episodes when the URL is a Spotify URL; otherwise an in-modal audio player when an `audioUrl` is available)
- The full description/summary text (not truncated)
- The publish date and view count (when available)
- A "Subscribe on YouTube" / "Follow on Spotify" CTA and a "View on YouTube" / "Listen on Spotify" CTA

All modal CTAs that represent navigation MUST be implemented as crawlable anchors:

- Each CTA MUST be an `<a>` element with a non-empty `href` attribute.
- The UI MUST NOT render placeholder `<a>` elements without `href` in the initial HTML.
- If CTA destinations are not known until a user selects an item, the CTA UI MUST be rendered as non-anchor elements until the destinations are known.

#### Scenario: User clicks a YouTube video card
- **WHEN** a user clicks a video content card on any listing surface
- **THEN** a modal dialog opens displaying a YouTube iframe embed, the video title, full description, date, view count (if available), and CTAs for "Subscribe on YouTube" and "View on YouTube"

#### Scenario: User clicks a podcast episode card with a Spotify URL
- **WHEN** a user clicks a podcast content card whose URL is a Spotify URL
- **THEN** a modal dialog opens displaying a Spotify episode embed, the episode title, full description, date, and CTAs for "Follow on Spotify" and "Listen on Spotify"

#### Scenario: User clicks a podcast episode card with a non-Spotify URL
- **WHEN** a user clicks a podcast content card whose URL is not a Spotify URL
- **THEN** the modal dialog opens displaying the episode metadata (title, description, date) and either:
  - an in-modal audio player when an `audioUrl` is available
  - otherwise, a "Listen on Spotify" outbound link

#### Scenario: Modal renders with missing optional fields
- **WHEN** a content item has no view count or no summary
- **THEN** the modal MUST still render cleanly with those fields omitted

#### Scenario: Modal CTAs are crawlable anchors
- **WHEN** the modal is present in the DOM (before any user interaction)
- **THEN** the document contains no `<a>` elements in the modal that are missing `href`

## ADDED Requirements

### Requirement: Embed fallback is a link only when a destination is available
If an embed fallback is presented as a link to an external page, it MUST be an anchor with a valid `href`. If no destination is available, the fallback MUST be hidden or rendered as non-link text.

#### Scenario: Embed fallback does not render a non-crawlable anchor
- **WHEN** the modal is rendered before any item selection
- **THEN** the embed fallback is not rendered as an anchor without `href`
