So the work started there — on set, in review sessions, inside Amazon's operational rhythm. Not arriving with a standard and enforcing it, but building one together in real time. Every constraint Amazon named became a design problem. Every rejected asset became a teaching moment. The playbook didn't precede the work — it accumulated from it, page by page, as both teams developed a shared eye.

That's the part that doesn't get documented: the moment two people standing in front of the same image finally see the same thing. That's when the vocabulary becomes shared. That's when the trust forms. That's what makes any document that follows actually useful.
