Support for your SaaS, installed with one prompt.

Install DeltaCrab support chat in this application.

Official integration guide (widget v1): https://deltacrab.com/en/docs
Machine-readable guide: https://deltacrab.com/llms-full.txt
Public site key: dc_pk_… (generated for your workspace)
Widget script: https://app.deltacrab.com/widget.js
No allowed origin is configured yet: tell the owner to add this app's origin in DeltaCrab → Install.

First inspect this repository and identify its framework, app entry point, routing,
authentication flow, Content Security Policy, and test/build commands. Read the
official integration guide before changing files. Use the documented script loader;
do not invent API endpoints or package names.

Install the widget once in the app's global layout. Start with visitor mode so
the chat works immediately. If this app already authenticates users and has a
trusted server runtime, implement the documented short-lived signed identity
endpoint on the server and connect login, logout, and account switching. Read
the customer ID from the verified server session. Never place signing secrets,
model keys, or privileged database keys in client code, prompts, or Git. The
signing secret must come from the DELTACRAB_IDENTITY_SECRET environment variable.

If the app sets a Content Security Policy, allow https://app.deltacrab.com in script-src,
frame-src and connect-src.

Use the app's current locale (en, pt-BR or es) and light/dark theme when supported.
Keep existing navigation and styling intact. If this platform cannot keep server
secrets, leave authenticated identity disabled and explain exactly what is required.

Run the existing build and relevant tests. Show the changed files, the result
of verification, any environment variable the owner must set, and how to send
a test message and verify it in DeltaCrab. Do not enable account-data tools
or AI auto-replies without the owner's explicit setup in the DeltaCrab panel.
