+## Purpose
+
+Define the media modal dialog behavior for in-page video and podcast previews.
+
+## 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
+
+#### 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
+
+### Requirement: Playback stops on modal close
+The modal MUST stop all media playback when it is dismissed, regardless of the dismissal method.
+
+The modal MUST support three dismissal methods:
+- Close button click
+- Pressing the `Escape` key
+- Clicking the backdrop outside the modal content
+
+After dismissal, no audio or video from the embedded player MUST continue playing.
+
+#### Scenario: User closes modal via close button
+- **WHEN** the modal is open with a playing YouTube video and the user clicks the close button
+- **THEN** the modal closes and the video playback stops immediately
+
+#### Scenario: User presses Escape while modal is open
+- **WHEN** the modal is open with a playing Spotify episode and the user presses the `Escape` key
+- **THEN** the modal closes and the audio playback stops immediately
+
+#### Scenario: User clicks the backdrop
+- **WHEN** the modal is open and the user clicks outside the modal content area (the backdrop)
+- **THEN** the modal closes and any active media playback stops immediately
+
+### Requirement: Modal accessibility
+The modal MUST conform to WCAG 2.2 AA dialog patterns:
+- The modal MUST use the native `<dialog>` element opened via `showModal()`
+- The modal MUST trap keyboard focus within the dialog while open
+- The modal MUST set `aria-modal="true"` and have an accessible label (via `aria-labelledby` referencing the title element)
+- Closing the modal MUST return focus to the element that triggered it (the card that was clicked)
+- The close button MUST have an accessible label (e.g., `aria-label="Close"`)
+
+#### Scenario: Focus is trapped within the modal
+- **WHEN** the modal is open and the user presses `Tab`
+- **THEN** focus cycles through the focusable elements within the modal and does not move to elements behind the modal
+
+#### Scenario: Focus returns to trigger on close
+- **WHEN** the user closes the modal
+- **THEN** focus returns to the card element that originally opened the modal
+
+### Requirement: Responsive modal layout
+The modal MUST be responsive across viewports:
+- On desktop viewports, the modal MUST be centered with a max-width that leaves visible backdrop on both sides
+- On mobile viewports (at or below the site's mobile breakpoint), the modal MUST expand to near-full viewport width with reduced padding
+- Embedded media MUST scale proportionally (16:9 aspect ratio for YouTube video, fixed height for Spotify embed)
+
+#### Scenario: Modal on desktop viewport
+- **WHEN** the modal is opened on a desktop viewport
+- **THEN** the modal is centered horizontally with backdrop visible and the video embed maintains a 16:9 aspect ratio
+
+#### Scenario: Modal on mobile viewport
+- **WHEN** the modal is opened on a mobile viewport
+- **THEN** the modal expands to near-full viewport width and the video embed scales to fit
+
+### Requirement: Embed loading state
+The modal MUST display a loading placeholder while the embedded media iframe is loading.
+
+#### Scenario: Iframe loading
+- **WHEN** the modal opens and the iframe has not yet loaded
+- **THEN** a placeholder (matching the site's card-placeholder style) is visible in the embed area until the iframe finishes loading
