SOP: Add language routing for a LATAM smartlink

A LATAM smartlink served one Spanish offer to all traffic. Brazil (Portuguese) was 27% of volume and converting poorly on a Spanish landing page.

Steps run:
— Step 1: Segment by country — BR EPC $0.09 vs Spanish-LATAM $0.28.
— Step 2: Confirm BR users were bouncing on the Spanish LP (high bounce in tracker).
— Step 3: Source a pt-BR offer; add rule country=BR OR accept-language=pt → Portuguese offer.
— Step 4: Keep es offers for the rest of LATAM.

Outcome over 14 days: BR EPC rose from $0.09 to $0.26 (+189%). Blended LATAM EPC up from $0.23 to $0.31. The fix was language, not geo — accept-language caught BR users browsing from other countries too.

Repeat monthly: check accept-language vs country mismatch; routing on country alone misses diaspora traffic.
