Replace emoji-based UI elements with consistent icons

What feature would you like to see added to viswam.ai?
Replace emojis used across the website with consistent SVG/icons.

Describe the feature in detail. Be clear about the use case and who it helps.
Some sections currently use emojis like 💻, 🎓, 🚀, and 📅 as visual elements. These should be replaced with proper icons to create a cleaner and more consistent UI for all users.

Why is this feature important or useful?
Icons look more professional, are easier to style, and render consistently across devices and browsers compared to emojis.

Any suggestions for how it could work or look? Add diagrams, examples, or references if possible.
A lightweight icon library like lucide-react can be used. For example:

• 💻 → Laptop
• 🎓 → GraduationCap
• 🚀 → Rocket

Additional context or notes
This is mainly a UI improvement that keeps the same meaning while making the website look more polished.
