The app's first streaming client: sse.js reads the /api/chat POST body
with fetch + a stream reader (apiCall's 60s JSON path cannot stream),
parsing SSE events with abort support. AiChatContext holds the
conversation (browser-only, per design) so it survives visiting the
Manage tab; switching modes starts a fresh conversation. The Chat tab
has the three-button mode picker, per-mode suggestion chips, streamed
answers with clickable relative WROLPi links, tool-activity indicators,
a slow-hardware banner, and a "not ready" state pointing at Manage.
ChatMessage states are in the theme-sample gallery.
