broll-web-capture

Produce the base layer of a technical reel: a website or GitHub repo turned into a short, animated B-roll clip. In a 40–60s reel a full live demo doesn't fit (it needs context and eats the runtime — reserve real demos for YouTube long-form). Complementary capture B-roll is the right register: a smooth zoom-in/pan or scroll over a crisp screenshot, illustrating while the narration/avatar carries the message.

Two-layer architecture (see the scene types in brand-content-strategy):

broll-web-capture / broll-terminal   ← BASE layer (proof visual)
        +
talking avatar in PiP                 ← OVERLAY layer (credential anchor)

This skill builds the base layer and, with --avatar, also composites the PiP overlay (via pip_overlay.py, the same compositor broll-demo-avatar reuses).
