Why:

• Vite 3.2.0 produces an empty JS bundle, only in production

Bundle contents:

(function(){const t=document.createElement("link").relList;if(t&&t.supports&&t.supports("modulepreload"))return;for(const e of document.querySelectorAll('link[rel="modulepreload"]'))n(e);new MutationObserver(e=>{for(const r of e)if(r.type==="childList")for(const o of r.addedNodes)o.tagName==="LINK"&&o.rel==="modulepreload"&&n(o)}).observe(document,{childList:!0,subtree:!0});function i(e){const r={};return e.integrity&&(r.integrity=e.integrity),e.referrerpolicy&&(r.referrerPolicy=e.referrerpolicy),e.crossorigin==="use-credentials"?r.credentials="include":e.crossorigin==="anonymous"?r.credentials="omit":r.credentials="same-origin",r}function n(e){if(e.ep)return;e.ep=!0;const r=i(e);fetch(e.href,r)}})();

Tried:

• drop svelte plugin
• only leave "console.log" in main.js

Partially undoes:

• Update dependencies; bump minimum node version to v18 #156
