When I install Prestashop via composer require prestashop/prestashop:^8 I get the following structure in the folder where the installation occurs:

root@localhost:prestashop-composer# tree . -L 1
.
├── composer.json
├── composer.lock
├── modules
├── themes
└── vendor

The rest of the Prestashop code I saw on github.com/PrestaShop/PrestaShop/tree/develop is placed in vendor/prestashop/prestashop. (Related: When I download Prestashop's ZIP distribution the traditional way, vendor/prestashop/prestashop doesn't exist there because all the Prestashop code is in the root directory.)

Composer decide to put only modules and themes here, and the rest in vendor? It must be indicated by some configuration file, but I can't find it.

I checked some contents:

• Checked packagist.org/packages/prestashop/prestashop to confirm that it indeed uses github.com/PrestaShop/PrestaShop/tree/develop as the source
• Searched Prestashop's Github for any mention of packagist
• Searched for information on how Composer determines folder structure but only found general information

(This problem is part of the "composer require prestashop/prestashop" installation, but some folders are missing)
