-- The firmware loads /.lua/main.lua into every fresh state and calls these on the
-- table it returns. Where apps live, what surrounds them and which of these an app
-- itself sees are all main.lua's to decide.
--
-- Fields the firmware reads: home, the route sys.back() lands on once history is
-- empty, and data, the sys.getAppDataPath() template whose ? is the app id.
--
-- The firmware does not clear the frame before calling draw(), and commits changed
-- display content after each callback batch using the panel's own refresh policy.
-- Timer callbacks are registered directly with timer.after/every.

---Required. Mounts the route; failing here leaves no app running.
---@param route string The app path sys.launch, sys.back or the boot recorded.
---@param arg? string The string passed to sys.launch or sys.replace.
function start(route, arg) end

---Optional frame loop, called once after start and then at most 30 FPS, best effort.
---@param deltaMs integer Monotonic milliseconds since the previous draw; zero on the first.
function draw(deltaMs) end
