You'll also need to run yarn build to generate the build assets

We can also test this out before merging if you want to tag this branch with v1.0.8 + update some repo to use the tag

very meta, but looks like this reformats to 4 spaces of indentation. monorail and optic both use 2 for ts. i don't particularly care, just calling out that departure.

edit: oh, i see prettier is complaining. i love how unhelpful "[warn] Code style issues found in the above file. Forgot to run Prettier?" is.

Well my editor doesn't seem to follow the project config, and also I ran yarn run format but the ci still complains -_- yarn lint passes locally as well, investigating

Ok so since no .prettierrc or equivalent is defined in the project, prettier was looking at my ~/.prettierrc config, which differs from the default prettier config used on the ci. I'm adding a prettier block in package.json
