   The following hardcoded values could map to global CSS variables from style.css:
   - #0f172a, #1e293b (background gradients) -> var(--bg-body) or var(--bg-main) in dark theme
   - #2563eb, #7c3aed (blob/icon gradients) -> var(--primary) and var(--accent)
   - #FFFFFF / white (text colors) -> var(--text-main)
   - rgba(255, 255, 255, 0.85) (border/text colors) -> var(--border) or var(--text-muted)
   - Alert colors like red/green/yellow -> var(--danger), var(--success), var(--warning)
