The firmware knew where apps, data and modules lived, called four globals,
and painted a status bar into a strip it clipped every app out of. None of
that was its business, and the viewport made the bar something an app could
neither compose with nor replace.
It now loads one file. main.lua mounts the route inside its own node tree,
so the bar is a sibling of the app rather than chrome painted over it: one
layout, one hit test, no inset arithmetic and no invalidation flags on the
C++ side. Apps and main.lua are tables -- they share a lua_State, so globals
would collide -- and a screen changes by rebuilding from node().
clang-format had no config here, so adopting the submodule's puts both repos
on the same pointer alignment. .editorconfig is what lua-language-server reads
on save, which is why the Lua tree had drifted between tabs and two widths.
Bluedroid cannot initialize beside the Lua runtime on this heap, so the
provider is NimBLE-Arduino. Scans keep the six strongest devices in a fixed
buffer rather than growing one. The standalone BLE app is gone: it was a
screen of toggles that belongs next to the other device settings.
