libavr's guidance binds this repo too, and until now nothing here checked it - `ctest` runs `libavr_format_test()` over this tree's own sources now (rules 11 and 33), skipping rather than passing where clang-format is absent. It caught drift on its first run: a file written this week and edited after formatting. Where the README states a measured size, `libavr_size_claim_test()` holds it to the image and holds the image to the prose: advancing the library pin moved three of these across the fleet with nothing saying so, and re-recording one now requires the sentence that quotes it to move too.
