/**
 * Action button. Renders as `<button>`, `<a>`, or `<RouterLink>` depending on props.
 *
 * 🤖 **AI Agent Usage Notes (Zero-Raw-HTML Adherence)**:
 * - ⛔ Do NOT add a `class` prop with Tailwind utilities (e.g., `w-full`, `mt-4`).
 * - To fill width, use `<LuButton full>`.
 * - To add margin, wrap in `<LuStack>` or a custom BEM container, do NOT apply margin classes directly.
 * - Visual theming is done exclusively via `--lu-*` CSS custom properties.
 *
 * @example
 * <LuButton variant="primary" @click="save">Save</LuButton>
 * <LuButton :to="{ name: 'home' }">Go Home</LuButton>
