The customer-page baseline

Small changes. Real pages.

Three simple pages for testing how experiments behave. The server renders everything you see; the baseline works even with JavaScript turned off.

01 / Appearance

A product card, ready for a published CSS experiment.

02 / Interaction

A working form, ready for a published JavaScript experiment.

03 / Non-match

A separate page that should stay unchanged by either sample.
