A/B runtime / 14 primitives + composition

A/B runtime + live experimentation primitives

Visual primitives for the Mufflermen workshop A/B runtime — built against real workshop experiments (Quote PDF redesign, Suburb landing CTA, Mobile dock vs sidebar). Primary metric is quote-accept rate; secondary is revenue per visitor. AU + NZ split. Visual reference only — no real backend wired.

Production answer

A/B runtime + live experimentation primitives is a reusable Oak Flats Muffler Men UI primitive with documented states, accessibility expectations, theme behavior, and implementation evidence.
