The bright, warm gradient and the bold "Summer Deal" text.

The video opens with a bright orange-red gradient background and the text "Summer Deal" in white. This transitions to a screen with the text "Abonnements mobiles illimités" (Unlimited mobile subscriptions) on the left, and a circle with "Dès 29.90 /m." (From 29.90 /m.) and a bar graph on the right. The next screen displays "Collectez des points avec chaque abo mobile et profitez-en." (Collect points with each mobile subscription and benefit from it.). The final screen shows "Sunrise Rewards" with a sunrise graphic, followed by a simple sunrise logo and the word "Sunrise". The pacing is quick and transitions are smooth.
