 - For native agent discovery, open `http://localhost:5184/editor/?webmcp=1` directly. WebMCP is document-scoped, so a browser agent does not inherit tools registered by the showcase's child iframe.
 - Translation, description generation, image generation, and model preparation may require browser AI support, WebGPU, model downloads, and several gigabytes of browser storage.
 - Unsplash and GIPHY search require their respective keys in **Settings > Media integrations**.
-- Publishing requires configured S3-compatible remote storage. The local MinIO settings in the project README are suitable for development.

 The current source routes public shares to `PublicDeckApp` before mounting `EditorApp`, while WebMCP registration lives in `EditorShell`. Therefore public attendee pages do not currently receive the editor tools or a public-view-specific WebMCP adapter. That separation is useful: add a dedicated public adapter instead of teaching the editor adapter about two unrelated authorization/state models.

+2. **Zero-setup publishing:** LocalStudio's current browser share service requires external S3-compatible storage configuration and user interaction. It is intentionally excluded from the authoring catalog until it can complete without hidden setup or external clicks.
 
 For the challenge build, prefer a narrowly scoped managed publisher—such as a small Cloudflare Worker issuing bounded upload capability URLs into R2—over shipping reusable writer credentials to the browser. Restrict size/content types, rate-limit creation, generate unguessable share IDs, and return a stable LocalStudio public URL. Keep bring-your-own S3 as the normal product path. If a managed publisher cannot be completed by the second build day, use a documented judge account/configuration flow and show it before the demo; do not hide a preconfigured local browser as if publishing were zero setup.

Then run the relevant editor/public coverage scopes, repo unit tests, typecheck, lint, and production builds. Cross-client acceptance must include ChatGPT's in-app browser and Chrome 149+ with WebMCP enabled.
