Extracted from @hanzo/ui pkg/ui/src/backends/svelte with its history. It lived inside a React component library, which meant every consumer of @hanzo/ui resolved svelte whether they rendered a single Svelte component or not, and the package declared peer svelte>=5 against a dev svelte ^4.2.20 — two answers to one question. Three runtime dependencies, all load-bearing: class-variance-authority for the variants the components already used, and clsx + tailwind-merge behind cn. The cn helper is vendored (17 lines) rather than imported back from @hanzo/ui, because depending on the package this was extracted from would undo the split. No design-system runtime, no icon pack, no CSS-in-JS. svelte-check: 50 files, 0 errors. Co-authored-by: Hanzo Dev <[email protected]>
