/*
 * Portfolio Tracker — Dark Glassmorphism Theme

 * Design language:
 *   - Deep navy/charcoal backgrounds
 *   - Frosted-glass cards (translucent with blur)
 *   - Teal/green accents for positive values
 *   - Red accents for negative values
 *   - Left sidebar navigation
 *
 * CSS custom properties (variables) are defined at :root so every component
 * can reference the same palette.  Change a variable here and it updates everywhere.
