## Purpose

Define a standardized card layout so content cards across surfaces look consistent.

## Requirements

### Requirement: Standard card information architecture
All content cards rendered by the site MUST use a standardized layout so cards across different surfaces look consistent.

The standard card layout MUST be:
- featured image displayed prominently at the top (when available), with a shimmer placeholder visible while the image loads
- title
- summary/excerpt text, trimmed to a fixed maximum length
- footer row showing:
  - publish date on the left
  - views when available (if omitted, the footer MUST still render cleanly)
  - the content source label (e.g., `youtube`, `podcast`, `blog`)

If a field is not available (for example, views for some sources), the card MUST still render cleanly with that field omitted.

#### Scenario: Card renders with all fields
- **WHEN** a content item has an image, title, summary, publish date, views, and source
- **THEN** the card renders those fields in the standard card layout order

#### Scenario: Card renders without views
- **WHEN** a content item has no views data
- **THEN** the card renders the footer bar with date + source and omits views without breaking the layout

#### Scenario: Card renders without featured image
- **WHEN** a content item has no featured image
- **THEN** the card renders a placeholder media area and still renders the remaining fields

#### Scenario: Card image shows shimmer while loading
- **WHEN** a content item has an image URL and the image has not yet loaded
- **THEN** the card media area displays an animated shimmer placeholder until the image loads and fades in

#### Scenario: Card image load failure shows static placeholder
- **WHEN** a content item has an image URL but the image fails to load
- **THEN** the card media area displays a static placeholder (no broken image icon) and the card remains visually intact
