Issue with deployment of a Laravel/Vite App with FTP

First of all, i just want to say that i’m a bit of a begginer when it comes to deployment of any kind of app on a Web cloud. Here’s my issue:

I have a Laravel 9 / Vitejs 4 app that i’m trying to deploy on an OVH Web cloud using only FTP. I used npm run build to build my app, and sent it to my cloud using FileZilla. Once in the cloud, i moved the index.php file from www/public to www and changed some line in it so it can refer to the correct files / folders.
But, and i don’t understand why, CSS won’t load and my login page appears as a pure HTML page. My css file (and js to) is in it’s own folder in www/public.

Here’s some files that could provide some clues:

app.blade.php :

<!doctype html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
<head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">

    <!-- CSRF Token -->
    <meta name="csrf-token" content="{{ csrf_token() }}">

    <title>{{ config('app.name', 'Laravel') }}</title>

    <!-- Fonts -->
    <link rel="dns-prefetch" href="//fonts.gstatic.com">
    <link href="https://fonts.bunny.net/css?family=Nunito" rel="stylesheet">

    <!-- Scripts -->
    @vite(['public/css/style.css', 'public/js/app.js'])
</head>
<body>
    [...]
</body>

vite.config.js :

import { defineConfig } from 'vite';
import laravel from 'laravel-vite-plugin';
import vue from '@vitejs/plugin-vue';

export default defineConfig({
    plugins: [
        laravel({
            input: [
                'public/css/style.css',
                'public/js/app.js',
            ],
            refresh: true,
        }),
        vue({
            template: {
                transformAssetUrls: {
                    base: null,
                    includeAbsolute: false,
                },
            },
        }),
    ],
    resolve: {
        alias: {
            vue: 'vue/dist/vue.esm-bundler.js',
        },
    },
});

index.php :

<?php
 
use IlluminateContractsHttpKernel;
use IlluminateHttpRequest;
 
define('LARAVEL_START', microtime(true));
 
/*

if (file_exists($maintenance = __DIR__.'/storage/framework/maintenance.php')) {
    require $maintenance;
}

*/
 
$app = require_once __DIR__.'/bootstrap/app.php';
 
$kernel = $app->make(Kernel::class);
 
$response = $kernel->handle(
    $request = Request::capture()
)->send();
 
$kernel->terminate($request, $response);

Thanks in advance!
