Modern Responsive Student Dashboard

I need a clean, modern-and-minimalistic student dashboard interface that scales gracefully on desktop screens. The core of this first release is a smooth, intuitive Message Center where students can read, search, and compose messages without feeling overwhelmed.

My priority is visual clarity: generous white space, subtle color accents for status cues, and typography that stays crisp on large monitors. Although the current scope is desktop, a responsive layout grid is still expected so future tablet or mobile breakouts won’t require a full redesign.

Please deliver:
• High-fidelity mock-ups (Figma, Sketch, or Adobe XD) covering the main dashboard shell and the full Message Center flow.
• Style guide with color palette, font stack, and reusable UI components.
• Optional bonus: lightweight HTML/CSS prototype to demonstrate responsiveness on common desktop breakpoints.

All assets should be handed off in editable form and organized layers so my development team can move straight into React implementation.
