/**
* The knowledge-context budget control (vision-context-injection.md) — the
* "session data" section's one input, shown where sessions START: the home
* (graph) view's new-session dock and the /chat/new draft. It renders in
* the StatsBar's LEFT slot — the very place session data (context/cost)
* lives once a session exists, which pre-chat is free real estate (just
* "—"). Input before output: the panel that will later show what the
* session contributed to the graph asks first what the graph will
* contribute to the session.
*
* One quiet compact row sized to sit in the stats band beside the model +
* thinking pills: short slider, "tok" readout (abbreviated — "4.1k tok"
* stays on one line where "4.1k tokens" wrapped). 0 = off; absent settings
* show the DEFAULT (1024 — on). The value rides ChatSettings (the same
* lifted settings the model picker uses), so it persists pre-chat via the
* same deferred PUT. Sessions never show this control — the injection is
* one-shot at session start, so mid-session there is nothing to decide.
