125  CRITICAL RULES:
126  1. Preserve the {option1|option2} spintax structure EXACTLY — same number of options, same positions
127  2. Keep ALL [placeholder] tokens unchanged: [firstname], [business_name], [domain], [grade], [score], [primary_weakness], [secondary_weakness], [impact], [keyword], [industry]
128  3. Keep \\n\\n paragraph breaks unchanged
129  4. The word STOP must remain in Latin characters — translate surrounding text only
130  5. Use ${formality}
131  6. Greeting should use "${greeting}" (replace G'day and Hi/Hello/Hey greetings with this; if localGreeting itself contains {|} spintax, keep it as-is)
132  7. Adapt marketing idioms naturally — don't translate literally if a natural ${langName} equivalent exists
133  8. Return ONLY the translated spintax, no explanation, no self-corrections, no "let me redo" statements
134  9. NEVER add opt-out, unsubscribe, or STOP instructions — email unsubscribe is handled separately
135  10. BRACE BALANCE: Count { and } in your input. Your output MUST have the EXACT SAME COUNT. The pattern {{greeting} [firstname|there]{,|!}\\n\\n|} is an outer optional-greeting wrapper — your output must start with { when input starts with {.
