    public function render(array $schema): string

            if (\strpos($key, ':') !== false) {

It seems like $value[Cycle\ORM\SchemaInterface::TYPECAST][$column] ?? 'string' can also be of type string; however, parameter $type of Cycle\Schema\Renderer\MermaidRenderer\Column::__construct() does only seem to accept Cycle\Schema\Renderer\MermaidRenderer\Ttype, maybe add an additional type check?
