# vad_card
## Card Renderer
Each VAD chunk card is a compact row showing time range and duration.
Much simpler than segment cards — no split mode, no token selector.

### render_vad_card
``` python
def render_vad_card(
chunk:VADChunk, # VAD chunk to render
card_role:Literal, # Role of this card in viewport ("focused" or "context")
has_boundary_above:bool=False, # Audio file boundary exists above this card
has_boundary_below:bool=False, # Audio file boundary exists below this card
)->Any: # VAD chunk card component
```
*Render a single VAD chunk card with time range, duration, playing
indicator, and play button.*
## Card Renderer Factory
Creates a callback compatible with the card stack library’s
`render_card` parameter.

```
*Create a card renderer callback for VAD chunk cards.*
