LiveryLab shared package export folder

This folder stores portable exports shared across LiveryLab workflows. It can
contain Advanced livery packages, Skin Packs, Workspace Transfer bundles,
Driver Profile packages, Tyre Brand packages, Numberplate template packages,
and Custom Grid presets.

Individual Official livery packages are exported to
OfficialLiveryPackageExport instead. Editable work never belongs in either
export folder:
- Advanced project files belong in LiveryProjects.
- Official project files belong in OfficialLiveryProjects.

Imported packages are added to LiveryLab locally first. They are not activated
in AC EVO until you explicitly use Activate in Game. Use Workspace Transfer
when you need to move complete editable projects to another installation.

Do not edit package manifests manually unless you are intentionally repairing
an export.

This README is managed by LiveryLab.
