参加証明書のデザイン

Create a formal certificate of participation in Spanish, with the same colorful and professional style as the reference invitation. The certificate should say 'CERTIFICADO DE PARTICIPACIÓN' at the top, then 'Otorgado a:' with a blank line for name, then 'Por su participación en la charla ACORDAMOS, RESOLVEMOS' with blank space for date and signatures. Use decorative borders, elegant typography, and include space for logos and signatures at the bottom. Clean, formal, celebratory design with colorful accents matching the reference.
