Give every capability its own concrete artifact:
Rewards Engine, Real-Time Triggers, and Segments each pair a plain-English pitch with an actual mini-interface: a reward bundle card showing "3,200,000 Gems · 18-hour cooldown," a grid of real trigger types (Install, First purchase, Session gap, Level milestone), and a tag cloud of segment names like "Whales · APAC" and "Comeback ready." Nothing here is illustrated abstractly - every claim has a visible, specific example sitting next to it.
