// snappy-frontend-dogfood/api.ts
//
// Frontend-driven dogfood loop for snappy-chat. Drive the running
// /Applications/SnappyChat.app via the head-screen server's chat-inject
// FIFO (not the raw API). This tests the ACTUAL UX: the React surface,
// the composer's submit flow, the sidebar state. Each journey is a realistic
// user scenario: welcome → starter chip → response card → verify sidebar.
//
// Captured screenshots are the ground truth. Return codes are meaningless.
