I Rot-13 the source code, you Rot-19 the output! This is alternate of a rip-off of a rip-off of a rip-off of a  rip-off of a rip-off of a rip-off. Go upvote those!
Your task, if you accept it, is to write a program/function that outputs/returns its input/args. But again, The tricky part is that if I rot-13 your source code, the output must be returned rot-19.
Your code will be only rotated once.
Examples
Let's say your source code is ABC and the input is xyz.
Code ABC should return xyz.
Code NOP(rotated) should return -./ (Rot-19).
Details

If your language has a custom codepage, apply rot13 to the bytes in the printable ASCII range in your code, and do not modify the rest. The input and output will be in pure printable ASCII.
The input only contains ASCII character.
use printable ASCII table for rotating
rot-13 means to forward 13 positions in ASCII table
Same applied to rot-19, which forward 19 positions instead.

Rules

Input can be taken in any convenient format.
Output can be in any convenient format as well.
Standard Loopholes are forbidden.

scoring
This is code-golf so the answer with the fewest amount of bytes wins.
Extra scoring rule
If there's somehow, a non-esolang appeared as a valid answer, it may considered as a better answer.
Example: python, C++, java script etc.
If you are confused with Rot
Here is a encoder to get some idea with.
Use full ACSII Table for this question’s requirement.
Use printable ASCII Table (33 ~126) for rotation!

Space are 32 in ASCII, which count as unprintable!
JavaScript (Node.js), 50 bytes

a=&gt;01+&quot;$25hYYXeya=&gt;z!`TcyV01yV~$'zv,'|&amp;&amp;z|xx-$&quot;&amp;&amp;a

Both versions are a function which takes a string as input and returns a string.
ROT13 code:
nJK=&gt;8/1?Buffer(nJK).map(c=&gt;(c-14)%94+33)+'':1/33n

Explanation
Hides tricky characters used in the ROT19 logic inside a string. The quotes map to / characters so it's just a matter of finding where to put them to make it work.
