Summary: Amberflo adds free trial and shifts to AI monetization

Why It Matters: The product is moving away from technical "control plane" language toward a direct focus on revenue and cost control. Adding a free trial also lowers the barrier for new users to start testing the platform without talking to sales first.

What Changed:

• Added a "Start Free Trial" button to the main navigation and header.
• Changed the main headline from "AI Control Plane" to "Monetize AI."
• Updated the sub-headline to emphasize "Usage-Based Pricing" and "Real-Time Cost Control."
• Simplified feature names, changing "AI Gateway & Access Control" to "Unified AI & LLM Cost Tracking."
• Removed "Prompt Optimization" from the primary feature list in the hero section.
