[LOW] Hardcoded external referral link

The advertisement link is a hardcoded URL that may need to be updated in the future. Consider extracting it to a configuration file or environment variable.

Suggestion: Move the referral link to a config file (e.g., public/constants.js) or an environment variable to ease future updates.

Risk: If the referral link changes, the banner will point to an invalid or unintended destination until the code is patched.

Confidence: 0.90
