/**
 * ═══════════════════════════════════════════════════════════════════════
 * Skills Sphere Visualization - Component Stylesheet (skills-sphere.css)
 * ═══════════════════════════════════════════════════════════════════════
 * 
 * PURPOSE:
 * Isolated styles for the interactive 3D skills network visualization.
 * Self-contained component designed for modularity and potential reuse
 * in other projects or as a standalone portfolio piece.
 * 
 * COMPONENT FEATURES:
 * - Interactive 3D sphere with drag-to-rotate, hover-to-explore
 * - Camera-relative label positioning (steepness-based adaptive offsets)
 * - Dynamic details panel with project/credential associations
 * - Category-based color coding (Core Analytics, Programming, Tools, ML)
 * - Theme-aware styling (seamless light/dark mode integration)
 * - Responsive layout with mobile optimizations
 * 
 * ARCHITECTURE:
 * - CSS Grid: Main layout (canvas + sidebar in 2-column grid)
 * - Flexbox: Internal component alignment (legend items, chips, lists)
 * - Absolute positioning: Overlays (instructions, attribution, node labels)
 * - Custom scrollbar: Hidden by default, appears on scroll activity
 * 
 * DESIGN SYSTEM:
 * - 12px border-radius for panels (matches website cards)
 * - Semi-transparent backgrounds with subtle borders
 * - 0 4px 16px shadows (consistent with main website aesthetic)
 * - Smooth 0.3s transitions for all interactive elements
 * 
 * DEPENDENCIES:
 * - CSS Variables from style-v2.css:
 *   • --primary-color: Accent color for interactive elements
 *   • --card-bg: Panel background colors
 *   • --text-color, --light-text-color: Typography colors
 *   • --shadow-color: Consistent shadow styling
 *   • --spacing-*, --border-radius-*: Layout tokens
 * 
 * - JavaScript:
 *   • skills-sphere-v2.js: Three.js rendering, interaction logic
 *   • skills-sphere-data-v2.js: Node/project/credential data
 * 
 * - External Libraries:
 *   • Three.js CDN (loaded in HTML)
 * 
 * THEME INTEGRATION:
 * - Inherits theme via [data-theme="dark"] and [data-theme="light"] selectors
 * - Uses rgba() with theme-specific opacity for borders/shadows
 * - Automatically adapts colors, borders, and scrollbars to active theme
 * 
 * RESPONSIVE BREAKPOINTS:
 * - 992px: Sidebar becomes scrollable, layout adjustments
 * - 768px: Single-column layout, mobile instructions, touch optimizations
 * - 480px: Further optimizations for very small screens
 * 
 * PERFORMANCE OPTIMIZATIONS:
 * - Minimal padding (4px) for maximum canvas size
 * - Scrollbar hidden until scroll activity (reduces visual clutter)
 * - GPU-accelerated transforms for smooth animations
 * - Will-change hints for interactive elements
 * 
 * MODULARITY:
 * This file can be extracted with skills-sphere-v2.js and
 * skills-sphere-data-v2.js to create a standalone component.
 * Only requirement: parent page must define base CSS variables
 * (--primary-color, --card-bg, --text-color, etc.)
 *
