study: give the Pro CTA a concrete value prop tied to the token-cost finding

The footer funnel asked for $9 Pro but described only the free core, so a
reader who just learned their agent bleeds 3,546 tok/turn had no stated reason
to upgrade. Add an honest one-paragraph Pro value prop (token metering + model
routing + 7 other production patterns) bridging the study's pain to the fix.
