major change, i know. now i'm using ssg and rssg by roman zolotarev.
okay, well, not exactly. ssg is modified to generate pages for gemini
too. it's hard to maintain two different things simultaneously.

bye-bye jekyll!

and modify the music-project layout to display those orphan tracks.

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

much of stuff included here is subject to change.

oops, i thought it'll work

remove .html from url

they are filled with temporary stuff, but this is the work for future.
