Embeddable snippet and A/B testing

Drop a one-line snippet on your storefront to feed Last Price live context, and run pricing variants through a new Experiments page with significance testing built in.

Two product surfaces that turn Last Price from "API you call" into "thing you ship to customers".

**Embed Snippet** page in the dashboard generates a single drop-in tag with your workspace ID baked in. The snippet streams observation events back to Last Price so your pricing functions see real demand, not just static config.

**Experiments / A/B Testing** page lets you split traffic across pricing variants, watch the allocator balance arms, and call the Elo significance built-in to decide when to declare a winner.

Both surfaces work with any pricing function in the marketplace, built-in or custom.
