/**
 * System › Integrations (#249 System S10 Task 27): the concept's `renderSystem` "integrations" body (app.js 682–684).
 *
 * - "ComfyUI": Default send destination, Host compatibility and Return to canvas after send. D106 (Q8): the send
 *   bridge always asks for the window and node, and the nodes always follow ComfyUI's own renderer, so only "Ask each
 *   time" and "Follow host renderer" can be chosen; the other options and the return toggle are disabled, with the
 *   reason under the row, and nothing is stored for them. Host compatibility also says which renderer the open
 *   ComfyUI windows use, as the send bridge reports it (`renderer` on each Prompt Manager node it lists).
 * - "LoRA & resources": "LoraManager integration" (enabled, a host draft) says where LoraManager was detected;
 *   D106 adds the read-only "LoraManager path" row, as on the legacy page. "Automatically include trigger words"
 *   (a host draft) says whether the trigger words are loaded. The three are separate facts (`/lora/status`).
 *   D114: the CivitAI key field is never filled in; typing drafts a new key, a blank field keeps the saved one, and
 *   "Clear saved key" (shown while a key is saved) drafts its removal; the line under it says "A key is saved." or "No key
 *   saved." All of them are
 *   saved by the one Save row (`/lora/enable` with the settings revision, system.mjs).
 * - "LoRA reference data" → "Review import" (D107; the concept's button only simulated a job): the server
 *   reviews the import (`POST /lora/import/preview`, read-only) and the shared review dialog shows what it replaces,
 *   what saved pairs block, what it downloads and the backup box; Start runs the "LoRA reference import" Activity job.
