composer.json:15

• tc-lib-pdf 8.73.6 and its tc-lib dependencies declare PHP ^8.2, so this package-level bump to ^8.3 is not required by the selected PDF engine and drops otherwise-supported PHP 8.2 consumers. Please keep the lower bound at ^8.2 and retain the corresponding CI coverage unless another dependency is the actual reason for the breaking change.

        "php": "^8.3",
