/**
 * Log Monitor Component Styles
 *
 * ARCHITECTURE: Collapsible panel at bottom of sidebar with monospace log display.
 *               Uses CSS Grid for log entry layout and transitions for smooth animations.
 *
 * WHY: Dark theme with monospace font provides familiar terminal-like experience.
 *      Level color-coding enables quick visual scanning for errors/warnings.
 *
 * TRADEOFF: Fixed column widths vs fluid layout. Fixed provides better alignment
 *           but may truncate long logger names. Acceptable for log viewing.
 *
 * NOTE: Uses existing variables.css theme tokens for consistency with app design.
