Field report (new tester, 510): keyboard A/D + arrows 'not working' --
can twist and drive but not turn. Root-caused live via key injection:
fresh spawns start in BASIC control mode, where steering rides the
STICK (authentic rookie mode) and the pedal-bound keys are inert by
design; one M press (MID) makes A/D steer. (A false regression-bisect
chase established the metric noise came from an attached pad's stick
drift nudging BASIC steering.) README now warns about the default
mode; kept the env-gated [padwrite] diagnostic from the hunt.
