/*
 * Fitly Utilities (fitly-utilities.css)
 * ═════════════════════════════════════
 * Fitly-specific utility classes that complement Bootstrap's
 * utility system. Loaded AFTER fitly-components.css.
 *
 * RULE: Before adding a class here, check if Bootstrap already
 * provides an equivalent utility (d-flex, gap-3, p-4, rounded-3,
 * text-body-secondary, etc.). Only add classes for concepts
 * Bootstrap does not cover.
