Argent Vega (Amazon Fire TV)

Critical

Vega is a TV platform
D-pad only. Drive every interaction with tv-remote. Never use gesture-* / touch — they are unsupported on Vega.
Always describe before navigating. Find the live cursor from the tree — the [focused] element, or [selected] when nothing reports [focused] (the toolkit often marks the highlighted item [selected] while focused stays false). Never guess focus position from a screenshot.
All tools take the Vega serial (from list-devices) as udid.

Per screen, two calls:

describe — find the cursor ([focused], or [selected] if no [focused]) and your target.
Compute the full D-pad path from focus → target (count rows/columns from the frames) and fire it as one tv-remote {button:[...]} ending in select.

Then describe again to confirm. On a miss, run the loop again.
