/* style.css for Catilu Solutions - Professional Revision */

/*
    MODIFICĂRI CHEIE:
    - Paletă de Culori: Înlocuit accentele neon (cyan, magenta) cu un albastru corporativ și tonuri neutre pentru un aspect serios.
    - Tipografie: Înlocuit fontul 'Orbitron' cu 'Poppins' pentru un look modern, dar mai profesional.
    - Elemente Vizuale: Redus opacitatea și complexitatea animațiilor pentru formele geometrice, făcându-le mai subtile.
