Take a stand against long quine lines or: Build a vertical quine

Inspired by Take a stand against long lines.

Your task is to build a vertical quine with as short a line length as possible.

Scoring

Shortest line length (excluding newlines) wins, with code-golf criteria as a tie-breaker.

Line length is determined as the longest line in your program excluding the line break character.

For example:

$_=
Q.
P


has a line length of 3 and a byte count of 8, whilst:

Q
$
_
P


Has a line length of 1 and a byte count of 7 (assuming no trailing newline).

Rules

Quines must meet the community definition of a quine.

Standard loopholes are forbidden.
Lenguage, line length 0, ≈ 1.01 × 10805 bytes

The source code is mostly identical to @jimmy23013's radiation-softened Lenguage quine, minus the . at the end, with ++++++++++.[-] replacing . to print linefeeds instead of null bytes, and the corresponding changes to the data section on line 1.
