+The colors swap, `color_low <--> color_max, color_mid <--> color_high` based on the user prefers setting by default. Set `swap_colors = false` to keep the same low-to-max color order in both light and dark modes.

 ## Important Notes
 
-- I originally wrote it in Typescript but thought go would be better to distribute to Hugo users (since you probably already have go installed) **so the go version is a completely vibed port**. I didn't look at the code, but it's probably fine? I did verify it's not sending credentials anywhere at least haha.

 - Private repo contributions are tracked, but they are anonymized in the activity.json. It shows up as `"private": "<count>"`.
 - I added Gitlab functionality but I don't use Gitlab so it may have issues. I set up a test account and did a quick test to make sure a new commit showed up, but good likelihood of edge cases.
