Web Chat is a WEB connection of a processing channel (SPEC-0003/ADR-0012),
reusing the whole contour: a public widget loads from the hub domain via one
async tag (<script src=hub.edevs.tech/chat-widget.js data-channel=...>), opens
an isolated iframe panel. Backend webchat app: public config/session/messages
endpoints (anonymous session, hash-at-rest token); inbound goes through the same
ingest (AI release + retrieval + handoff + notifications); WEB transport send is
a no-op (browser polls). Panel rebuilt 1:1 from the baseline (welcome+consent /
ai / operator / unavailable, quick replies, typing). nginx serves /chat-widget.js
and /chat/ from the hub domain; demo host page at /chat/demo.html. Verified
end-to-end: config→session→message→AI reply→poll.

Public checkout belongs to product backends, not Hub (ADR-HUB-0014,
ADR-HUB-0018). Delete apps/checkout and its wiring: compose service, nginx
pay.localhost route, npm workspace and dev script, playwright project,
HubApplication type, check.ps1 typecheck and README mentions.
