Text under image
| this is how you make an image slide with text
| image takes TOP    70% of space
|  text takes BOTTOM 30% of space


| this comment is going to be fully omitted


Text you type
  here is going
    to be scaled
automatically to
      fit the slide
| Those spaces at the line start are preserved.


```
use crate::theming::*;

async fn main() {
    let config = Config::from_file();
    let mut font: Font = if let Some(path) = &config.font_path {
        let data = std::fs::read(path).expect("Failed to read font file from config");

| Codeblock example
| use ``` at the start of the block
|         and ``` at the end of the block to create one.
