/*
 * Design system definition.
 *
 * The @theme inline block maps CSS custom properties to Tailwind utility
 * classes (e.g. --color-primary -> bg-primary, text-primary).
 *
 * The :root and .dark blocks define the actual color values using oklch.
 * All colors MUST use oklch format.
 *
 * To add a new semantic color:
 * 1. Add the variable to :root (light value) and .dark (dark value)
 * 2. Register it in @theme inline as --color-<name>: var(--<name>)
