Add an endBeforeStart $derived to WhoWhenSection (lexicographic ISO compare, no Date object) that renders an inline error on the end-date field — border-red-400, aria-invalid, aria-describedby, and a #end-date-error <p> inside the existing aria-live region — with a ⚠ glyph so the cue is not colour-alone (WCAG 1.4.1). Save is not disabled; the server stays the gate. Wire ErrorCode INVALID_DATE_RANGE through errors.ts getErrorMessage and add the single key error_invalid_date_range to de/en/es, so the same translated string is used inline (client) and via getErrorMessage (server fallback).

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.
