Experiment Test Page
One card per experiment registered against this route. Each card lists the experiment slug, the PR that introduced it, and any audience constraints. The middleware mutates the card body for visitors bucketed into a non-baseline variation. CTAs fire the experiment's primary goal via the click registry.

Control top
Top region — control content shows by default.
VARIANT TOP
A bigger top headline
The variant component for the top socket — this region is fully replaced when bucketed into variant. The middle stays put.
Stable middle — this region never changes regardless of bucketing. It sits between two swappable regions to demonstrate independent slots within the same card.
Control bottom
Bottom region — a baseline marketing block. The variant swaps this entire layout for a different one.
- Original feature one
- Original feature two
- Original feature three
Variant component (e2e-component-swap-test)
The variant replaced the entire body — different heading, different copy, different layout. Both trees are rendered server-side; the middleware just toggles which is visible.
