- [x] Steps in

## Overview

Things that need to work for this PR:

- [x] Core `emoji-blast` and `konami-emoji-blast` libraries
- [x] Integrations: Astro, React, TypeDoc
- [x] Knip
- [x] Linting
- [x] Testing
- [x] TypeScript project references: used instead of tsup for `lib/`
outputs and type checking
- [x] Webpack builds: for `dist/`, since the existing projects generally
used it

Things I'm leaving as followups:

- https://github.com/cgradeff/emojisplosion-site
- Release management: I'm thinking Changesets
- Investigating switching from Webpack to something newer/faster
- Test coverage

-Each corresponds to a Webpack ["entry point"](https://webpack.js.org/concepts/entry-points) under under the same name.
+You should also see suggestions from TypeScript in your editor.

+### Individual Packages
 
-```shell
-pnpm build:dist

+Note that some individual packages also have their own `build` command.
+Each package `build` runs [webpack](https://webpack.js.org) to build source files from `src/` into output files in `dist/`.
 
-Add `--watch` to run the builder in a watch mode:
+You can run them all from the root with:
 
 ```shell
-pnpm build:dist --watch
+pnpm build:all
 ```
 
+See each package's `.github/DEVELOPMENT.md` for per-package building instructions.
