Assistant replies can now emit typed fenced blocks that render as
@crema/*-ui components inline at their position in the reply.
- message-body.tsx: segmented rendering — alternating prose chunks and
block dispatch (was: all blocks appended at end). Renderers for kpi,
table, chart-bar/-line/-donut/-spark, code, diff, flowchart, orgchart,
steps, checklist, welcome, hint, plus the legacy card kinds.
- block-schemas.ts: single source of truth — BLOCK_INDEX (one-line
purpose per kind, always in prompt) + SCHEMAS (full JSON shape +
example, fetched on demand).
- admin-tools.ts: new get_block_schema(kind) tool the model calls once
per kind per thread to fetch the exact schema. Keeps the always-on
prompt small (~110 tokens vs ~400 inline).
- assistant.tsx: replaces the inline schema dump with the generated
thin index.
- ai.tsx: empty-state preview button injects a synthetic assistant
message exercising every block, for renderer/theme smoke-testing.
- console.css + ai.tsx: shrink ATLAS headline so it doesn't slip under
the composer with the added preview button.
- tsconfig.json + app.css: wire lib-data-ui, lib-code-ui, lib-diagram-ui,
lib-onboarding-ui as siblings.
Adding a new block kind = add the lib paths, add a renderer case, add
a schema entry. No prompt edits required.
