The pin crosses libavr's phase-6 close and the guideline sweep behind it;
the image is byte-identical in both modes at 8206 bytes.
The port's own sweep, against the same rules. Every mutable `static inline`
takes `m_` - uptime's counter, the sampler's window, the controller's five,
the statistics histogram and the terminal's line state (rule 46; a private
`static constexpr` is a constant rather than state and keeps its bare name).
The command table is `std::to_array` and the serial config breaks one member
per line (rules 36, 40). And three numbers get the name they already had
somewhere: duty goes through `percent_t::of()` rather than a hand-built
basis-point count, the ADC's top count is `thermistor::adc_full_scale`
instead of 1023 in four places, and the two `0xffffffff` are `open_circuit`
- which was already declared five lines away - and `never_written`, which
replaces a comment explaining the literal (rules 5, 6, 41).
Measured, not assumed: rendering `adc_full_scale` into the `show` line
instead of leaving it in the message string cost 6 bytes, so the display
text stays text.

The renames land (interrupt_guard, consume_reset_cause, set_duty), the
sampler binds its input in the new converter shape (the input pack plus
in<>::start() as free-running's one kick), and the console states
.allow_baud_error = true for the 115200-at-16-MHz this board has always
spoken - the receiver-tolerance table libavr now enforces is stricter
than the rate's own +2.1 %. The loader probe reads through
avr::flash_load instead of raw pgmspace, the terminal's line buffer is
std::array with backspace and delete named, the tree is reformatted
under InsertBraces, and the sources are ASCII.

Same controller: thermistor on ADC0 averaged over 1000 free-running
conversions, 50 kHz fan PWM on OC0B, 115200 Bd console with the full
command set, EEPROM temperature histogram, watchdog-reset path into the
boot section. The Steinhart-Hart math and the libm log are gone — the
Beta equation and the cubic fan curve are consteval-evaluated into
flash tables; the firmware never does floating point. Byte-identical
.text in both libavr modes. Legacy stays on master.
