Replace Earth intro with Antananarivo parachute-drop video

Swap the rotating Earth backdrop for an AI-generated golden-hour shot
of Antananarivo's skyline with navy cardboard boxes parachuting in
from across the frame. The hero box at center gets the MVA Global Fret
shield overlaid for the last second of the loop, so each cycle ends
on a brand reveal.

Pipeline: source video cropped (bottom 150px) to remove the HeyGen
watermark, audio stripped, MVA logo composited on the foreground box
from t=4 to t=5 with a 0.3s alpha fade-in, re-encoded to H.264 at CRF
22 (1.1 MB total).

Tint overlay softened — the original navy gradient was tuned for the
dark space backdrop and was crushing the golden hour light.
