Move the layout function out of StammbaumTree.svelte (lines 47-275) into a new pure TypeScript module at frontend/src/lib/person/genealogy/layout/ buildLayout.ts so it can be exercised by direct unit tests. Drops the eslint-disable svelte/prefer-svelte-reactivity blanket; switches the remaining scope-local Maps/Sets in parentLinks to SvelteMap/SvelteSet to satisfy the rule per-call-site. No behaviour change — existing StammbaumTree tests must pass byte-for-byte. Refs #689 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
sv
Everything you need to build a Svelte project, powered by sv.
Creating a project
If you're seeing this, you've probably already done this step. Congrats!
# create a new project in the current directory
npx sv create
# create a new project in my-app
npx sv create my-app
Developing
Once you've created a project and installed dependencies with npm install (or pnpm install or yarn), start a development server:
npm run dev
# or start the server and open the app in a new browser tab
npm run dev -- --open
Building
To create a production version of your app:
npm run build
You can preview the production build with npm run preview.
To deploy your app, you may need to install an adapter for your target environment.
