Create a finished, legible event logo in a square format. Build a circular magical seal with a fine ornamental border, like an insignia stamped into an ancient spellbook. At the center, set the exact headline “INFUNSEC” in large, highly legible Celtic knotwork display capitals: broad, balanced strokes formed from continuous interlaced ribbon bands, weaving over and under at crossings; subtle carved-stone depth; restrained triquetra and spiral terminals. Keep the letter skeleton clear beneath the ornament. Give the ribbons an aged gold surface with fine engraved lines and glowing violet light caught inside the weave. Arrange the exact supporting text “SEGURANÇA DIGITAL” in small refined capitals along the upper arc of the seal. Set “CONHECIMENTO • DEFESA • MAGIA” along the lower arc, evenly spaced and easy to read. Center a small open spellbook emblem beneath the main word, its pages etched with a simple shield-shaped rune; keep it secondary to the name. Use elegant fantasy serif lettering for the supporting lines, with crisp edges and restrained gold highlights. Surround the seal with small glowing arcane runes and magical symbols orbiting in loose, asymmetrical paths, leaving visible space around the lettering. Add fine golden particle trails, floating sparkles, and delicate wisps of purple smoke. Use a deep plum-black spellbook background with subtle worn leather grain, faint shadowed library shelves, and a few warm candle glints. Purple and gold magical light interplay against deep shadow; soft halos and upward light from below give the mark depth. Keep the logo clearly framed, balanced, and readable at small size. No extra words, no mockup, no watermark.
