/**
 * Panels - Panel component (Bootstrap 3 legacy component)
 *
 * Note: Uses @size-* tokens for spacing; @font-size-* tokens for typography, and panel component variables.
 *
 * Intentionally hardcoded values:
 * - Off-token spacing (15px): Legacy padding not in token system
 * - Border widths (1px, 2px): Standard borders and outlines
 * - Negative offsets (-1px, -2px): Fine-tuning
 * - Percentages (100%): Layout
 * - Line-height values (1, 1.1): Unitless ratios
 * - Opacity values: Visual states
 * - Transition durations (0.2s, 0.35s): Animation timing
 * - Box-shadow values: Elevation effects
 * - RGBA values: Transparency
