Typing /context in the composer opens a centered dialog with the current composition (provider-anchored headline, stacked bar, legend) and the last-10-turn trend chart — the same pushed contextTimeline projection the tab renders, no RPC, no polling. The command is the plugin's own '/' trigger source, fully client-side: no host descriptor, no session log records, nothing model-visible. The composer token is consumed only when the modal closes (deferred slash/input-consume-token with span / bare-token guards, fail-soft if the draft changed meanwhile). Esc, backdrop click, and the close button all close it and restore composer focus. Also extracts the provider-anchored headline derivation shared by the tab and the modal (headline.ts).

/**
|
|
* `/context` — a client-owned slash command that opens the context modal
|
|
* (current composition + recent trend) in the center of the page.
|
|
*
|
|
* Implemented as the plugin's own '/' trigger source instead of a host
|
|
* command: nothing is dispatched to the host, no session log records are
|
|
* written, and nothing becomes model-visible — the invocation never enters
|
|
* the message history. Both paths answer `'handled'` and open the modal,
|
|
* leaving the `/context` token in the composer while it is open; the modal's
|
|
* close path consumes the token then (see modalStore.ts).
