/**
 * Range Display - Visual range/gauge display component
 *
 * Note: Uses @size-* tokens for spacing and positioning; @component-* variables for colors.
 * File has been optimized with mixins for repeated selector patterns (lines 3-32).
 *
 * Intentionally hardcoded values:
 * - Component-specific dimensions (240px, 300px, 44px, 80px): Fixed component sizes
 * - Off-grid spacing (2px, 3px, 6px, 9px, 11px, 14px, 26px, 28px, 30px, 34px, 37px, 38px, 54px, 56px, 105px): Component-specific positioning and sizing
 * - Border widths (1px, 2px, 3px): Standard and component-specific borders
 * - Font-sizes (11px): Off-grid typography
 * - Percentages (50%, 100%): Layout and positioning
 * - Calc expressions: Complex computed values with CSS custom properties
 * - Transform values: Positioning adjustments
 * - Z-index values: Stacking order
 * - Opacity values: Visual effects
 * - Transition durations: Animation timing
