/**
 * Utility Classes
 * Layout, spacing, and responsive utilities for the universal design system
 */

/*
 * Legacy copies of Tailwind classes (same meaning as Tailwind's). Mobile review
 * slice 8b moved them into a cascade layer BELOW Tailwind's `utilities` layer
 * (tailwind.css, loaded first, fixes the order: properties, theme, base,
 * components, utilities). Unlayered, they beat Tailwind outright, so responsive
 * / state variants (sm:flex-nowrap, md:grid-cols-12, hover:shadow-lg,
 * focus:ring-*, border-{color}, duration-*) silently did nothing. Where
 * Tailwind compiles the class it now wins; where it doesn't, these still apply.
 *
 * Border colour: Tailwind's .border / .border-t set width + style only; the
 * layered legacy .border / .border-t below still supply the faint grey colour
 * (components layer), and authored border-{color} utilities now override it.
 *
 * Kept UNLAYERED below on purpose (different meaning or element-selector risk):
 * .text-secondary (grey here, crimson in Tailwind), .bg-tertiary (grey vs cyan),
 * .rounded (0.5rem vs 0.25rem), .text-sm / .text-xs, and every custom class
 * (.d-flex, .mb-md, .gap-md, …) that has no Tailwind twin.
