/* ============================================================
   PhishGuard — style.css  (FIXED)
   Key fixes:
   1. font-family REMOVED from * selector — was breaking Font Awesome icons
   2. font-family applied to body only (inherits correctly)
   3. Stats dashboard grid fixed — 4 equal columns, no orphan card
   4. Stats dashboard no longer overlaps hero (margin-top removed)
   5. Navbar mobile wrap fixed
   6. All icon elements (i, .fa, .fas etc.) explicitly excluded from font override
