/* ==========  COMPONENT UTILITIES  ========== */
/* Reusable classes to replace inline styles throughout the application */

/*
 * NAMING CONVENTION:
 * - Properties use standard CSS names (m = margin, p = padding, w = width)
 * - Directions: t = top, b = bottom, l = left, r = right, x = horizontal, y = vertical
 * - Values use hyphens for decimals: 0-5 = 0.5rem, 1-5 = 1.5rem
 * - Integer values: 0, 1, 2, 3 map directly to rem values
 * 
 * SPACING SCALE:
 * - 0    = 0
 * - 0-5  = 0.5rem  (8px)
 * - 0-75 = 0.75rem (12px)
 * - 1    = 1rem    (16px)
 * - 1-5  = 1.5rem  (24px)
 * - 2    = 2rem    (32px)
 * - 3    = 3rem    (48px)
 * 
 * EXAMPLES:
 * - .mt-1-5  = margin-top: 1.5rem
 * - .px-2    = padding-left and padding-right: 2rem
 * - .mb-0-75 = margin-bottom: 0.75rem
 * - .my-1    = margin-top and margin-bottom: 1rem
