Tester #5506 §2 + Markus #5504 §2: the 409 orchestration was inline in +page.svelte and untested. Extract into a pure module that takes the fetch function as a dependency, so the full happy path / 409 path / 500 path / refetch-fails path / UUID-guard path can be unit-tested with mock Responses. The route file now reads as 12 lines: call the helper, on conflict apply the merged snapshot to local state, re-throw. BlockConflictResolvedError now carries the merged block on its `merged` property so callers don't have to redo the refetch. 6 new unit tests cover every branch.

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.
