Gave my "Tracing Without the Tax" talk at @nodeconf.eu
in Bologna 🇮🇹

Thanks to every maintainer and reviewer who pushed with us 🙏

![A snippet of code:
```
// directives/haptic.ts
type Modifiers = 'light' | 'medium' | 'heavy';
export const directive: Directive<HTMLElement, undefined, Modifiers> = {
mounted(el, { modifiers }) {
el.addEventListener('mousedown', () => {
Haptics.impact({ style: Object.keys(modifiers)[0] || 'light' });
});
},
};
// env.d.ts
declare module 'vue' {
// ...
export interface ComponentCustomProperties {
vHaptic: typeof import('./directives/haptic').directive;
}
}
