- /api/loaded backend endpoint proxies Ollama /api/ps and returns
{models: [{name, expires_at}]}
- Status line under the controls shows "Hot: gemma2:9b — unloads in 4m"
with a glowing orange dot, or "No model loaded" in muted style
- Loaded models in the dropdown get a "● " prefix
- Refreshes on page load, after every translation, and 500ms after the
user pauses typing in the input box
