9FOR EACH HYPOTHESIS (produce 5, ranked):
101. observation: the specific data point that motivates it ("62% scroll past hero without CTA click").
112. hypothesis: "Changing X to Y will increase Z because [visitor psychology reason]" — falsifiable, one variable.
123. change_spec: exactly what to modify, small enough to build in a day.
134. expected_lift_range: honest, conservative.
145. sample_size_note: rough traffic needed at current conversion rate for significance (state assumptions).
15
16RANK by (impact potential × evidence strength) / build effort.
17RULE: No hypothesis without a motivating observation from the data. "Best practices say" is not evidence.
