Run locally

# Install dependencies
pnpm install

pnpm dev

Build for production

pnpm build:browser
# Output: apps/desktop/dist/

Tests

# Build workspace packages first — @flash/* packages resolve to ./dist/index.js, so
# cross-package imports fail in tests until dist/ exists.
pnpm --filter './packages/**' build

# Unit tests (run sequentially to avoid esbuild race)
pnpm --filter @flash/swf run test -- --run
pnpm --filter @flash/core run test -- --run
pnpm --filter @flash/authoring-ui run test -- --run

# E2E (Playwright — auto-starts Vite dev server on port 1420)
pnpm --filter @flash/desktop e2e
