Overall Potential Residency Outcome (Illustrative):

`; if (finalResidency.startsWith('Likely')) { resultText += `

Based on the simplified analysis and common principles, residency is ${finalResidency}.

`; } else if (finalResidency === "Mutual Agreement Needed" || finalResidency === "Tie-Breaker Inconclusive") { resultText += `

The tie-breaker analysis was inconclusive based on the provided information. Residency might be determined by mutual agreement between the countries' tax authorities.

`; } else { resultText += `

Based on the simplified analysis, potential residency appears to be in: ${finalResidency}.
