colijn-core

Code shared by the Colijn tools (Colijn++, ColijnSPICE): Rust only, egui on wgpu, desktop and web. A new tool starts from crates/starter; agents: read docs/agent-guide.md first, it is the whole contract.

Part	What it is
crates/ui	colijn-ui: theme, fonts, icons, widgets, and the frame every tool has (brand, splash, start page, About, Save changes?, shortcuts, toasts, Ctrl+K palette, searchable Settings, copy as a picture, desktop start-up), plus the skin hook
crates/retro	colijn-retro: retro mode, a classic bevelled look as a skin of colijn-ui
crates/update	Online updates: signed manifest, checked download, in-place install with rollback, background Updater. No egui.
crates/update-egui	The update notice, the Updates settings and the About version line
crates/starter	The smallest Colijn tool: the template for a new one, with a UI test
tools/release	colijn-release: signing key, package zips, signed latest.json
tools/fonts	build.py: the Lucide subset and retro mode's icon font, from the Rust sources
