lottie-web renders vector animations from a JSON document at runtime. As third-party JS it falls outside the declarative CSS path and the WAAPI / reveal / marquee probes, so clones shipped the empty container and the animation was gone. This adds a Lottie subset to Stage 5 motion: capture the deterministic part — the source JSON (materialized local file, or inline animationData) plus playback config — and emit a fixed DittoLottie client that re-mounts lottie-web on the cid'd container. Capture (compiler/src/capture/lottie.ts): in-page detector covering lottie-web's registry (animationData in memory), <lottie-player>/<dotlottie-player>, Elementor data-settings (source_json.url), and generic markup. Keyed by data-cid-cap. motion.ts merges it into MotionCapture; capture.ts registers source URLs as assets so the existing fallback fetch downloads + materializes them to /assets/cloned/lottie. Generate (compiler/src/generate/lottie.ts): buildLottieSpec resolves cap->cid and source URL->materialized local path (or embeds inline animationData), then emits DittoLottie + wire/import helpers, mirroring DittoMotion. app.ts writes the component, wires import+JSX, and injects lottie-web into the generated package.json. Delivery (compiler/src/cli.ts): stripDeliveryDataCids now treats DittoLottie as a runtime consumer, so its container keeps a semantic data-ditto-id anchor instead of being stripped (without this the animation never finds its mount point). Lottie-free clones stay byte-identical. Verified end-to-end: cloning a page with a <lottie-player> scrapes the JSON, emits a wired DittoLottie, and lottie-web mounts and plays the captured animation (rendered SVG viewBox matches the source JSON). Unit tests cover buildLottieSpec resolution + drop rules. Co-Authored-By: claude-flow <ruv@ruv.net>
ditto.site Compiler
This workspace contains the deterministic compiler used by ditto.site. It captures a source URL, builds a render IR, infers assets/fonts/tokens/sections/recipes/SEO, generates a Next.js App Router app by default or a Vite React app on request, and validates the result with deterministic gates.
The full architecture overview lives in ../README.md. This file keeps only compiler-local commands and notes.
Commands
cd compiler
npm install
npx playwright install chromium
npm run clone -- https://example.com/
npm run clone -- https://example.com/ --mode=multi --styling=tailwind

npm run typecheck
Root-level scripts forward to these commands, so npm run clone -- <url> works
from the repository root too.
Multi-page generation defaults to the fast no-validation path. Use --validate
when the clone command itself should run the full build/render/gates QA pass, or
run validate-site separately. --concurrency controls source route capture;
--validate-concurrency controls how many routes validation grades at once; and
--viewport-concurrency controls how many clone viewports each route renders at
once.
Generated App Shape
Default Next generated apps use src/app/ditto.css and optional helpers under
src/app/ditto/. Vite generated apps use src/ditto.css and optional helpers
under src/ditto/, with multi-route pages under src/routes/. Validation builds
keep data-cid attributes for source/clone alignment; delivered apps strip those
validation ids and keep only required data-ditto-id anchors.
