A pub workspace of the Dart packages Halkyon's apps share: halkyon_ui, Halkyon's look (the theme, fonts, layout and shared widgets, with texts in English and German), halkyon_core's low-level primitives and halkyon_interop's cross-app contracts. Dart 3.13 with LeanCode's lints, configured once at the root; apps take a package by git, pinned to a signed commit.
