EmbedFlow deterministic demo (offline)
======================================

$ embedflow demo --path ./demo-runtime --no-serve
T2-v1 diagnostic: SAFE; recommended K=10
Demo ready at ./demo-runtime/embedflow.yaml

$ embedflow search --config ./demo-runtime/embedflow.yaml --demo \
    "what explains auroras?" --top-k 3
state: COLD   source candidates: 10   cache: 0/10   queued: 8

... background materializer runs ...

$ embedflow search --config ./demo-runtime/embedflow.yaml --demo \
    "what explains auroras?" --top-k 3
state: WARM   source candidates: 10   cache: 10/10   queued: 0

The exact state and latency values depend on the local machine. This still is
an illustrative terminal still, not a performance claim.
