daaaaaaaamn. 13 is the demonic number indeed.

'cause it contains only liquid script and not a single line of html.

music info is messed up now, but kinda works

also snippet that makes art menu is now separated as mixin (very
powerful thing, btw).

sadly it doesn't work with each visit to the website, but i don't want
to include javascript into the website.

thumbnails are currently created using shell script and require
imagemagick installed on the server. i know it's stupid, but i think
that including thumbnails to repo is also stupid.

maybe later i replace this script with actual jekyll plugin, but for
this i'll need to familiarize myself with ruby.
but now i use following addition to the git hook on the server:

```
[ -f "$TMP_GIT_CLONE/art/thumbs.sh" ] && {
    dir="$PWD"
    cd "$TMP_GIT_CLONE/art/" && sh thumbs.sh && cd "$dir"
}
```

it happens after cloning to remote repo and before building with bundle.

overall, this is a bodge now, it recompiles all thumbnails every time
due to quirks in my current setup.

add two new categories - drawings and logos.

this css tinkering is so time consuming >_<

forgot to include pic-path tempate to the art page
