Previously the lede oversold conformance ("A demo of the A2UI
protocol") when the repo used a flattened application envelope.
PR #4 closed that gap — the demo now genuinely emits v0.8
surfaceUpdate/beginRendering messages, uses the official standard
catalog for chrome (Text/Button/Row/Column/Card/etc.) over the
canonical catalogId, and reserves a namespaced custom catalog
(lumen.com:concierge/v1) for the three e-commerce composites.
This README update:
• lede now describes the v0.8 implementation accurately, linking
to google/A2UI and the official standard catalog definition
• the "Five A2UI components" bullet is replaced with the
two-catalog model (standard for chrome, custom for composites)
and a pointer to docs/a2ui-shapes.md
• surface count bumped from two to three (Android, iOS, web)
reflecting the KMP migration in PR #5
• model framing softened to "LiteLLM, defaults to Claude" to
match the actual configurable provider
Closes the work tracked in #6 (which had a stop-gap "inspired by"
framing while PR #4 was open). #6 is closed as superseded.

Summary
PR #4 made A2UI v0.8 conformance real. This PR updates the README lede to say so accurately, without overclaiming.
What changes
surfaceUpdate/beginRendering/dataModelUpdate/deleteSurface), official standard catalog (Text/Button/Row/Column/Card/CheckBox/TextField/MultipleChoice/Divider) at the canonical catalogId, plus a namespaced custom catalog (lumen.com:concierge/v1) for the three e-commerce composites (CardGrid,ProductDetail,PaymentChallenge). Links to google/A2UI and the standard catalog definition.docs/a2ui-shapes.md.Why now
Hanlu flagged the original lede as overclaiming. I opened #6 with a stop-gap "inspired by" disclaimer while #4 was in flight. #4 is now merged — the framing in this PR is the right one. #6 is closed as superseded.
