Upgrade ArduinoHA from 1.3.0 to 2.1.0 and rewrite mqtt.ino for it.
The clock now shows up in Home Assistant (discovery prefix
"homeassistant") with:
- switches Tubes (blank the display, runtime only) and Auto dim
- numbers Day/Night brightness
- light Backlight (on/off, brightness, RGB mapped to the colour wheel)
- select LED effect, button Cathode protect
- sensors Light (LDR) and WiFi signal, plus the upstream sensors when
the clock has them; master-clock subscriptions are kept
Settings changed from HA are saved to EEPROM 3 s after the last change.
Fixes the unbounded memcpy in the MQTT message handler.

Adds CLOCK_90 and the nixie595.ino driver: two 74HC595s on hardware
SPI (GPIO13/14, latch GPIO15), multiplexed from an IRAM-only timer1
ISR. Neon dots on P1; P2 is the decimal-point line on this board.
Also:
- NeoPixel on any ESP8266 pin via bit-bang (GPIO12), and take the pin
back after SPI.begin() claimed it as MISO
- ArduinoOTA (USE_ARDUINO_OTA), with an OTA upload env in platformio.ini
- DST: EU end date (last Sunday of October) instead of the first Sunday
of November, and recompute the time from the rules when DST is
toggled instead of shifting it by 1 h
- forward declarations so PlatformIO's .ino conversion compiles
- FIRMWARE_SERVER can be overridden; empty for CLOCK_90
Verified on the clock: tubes, order, dots, LEDs, LDR, NTP time with DST.

Disassembled the SV1.3 app image and confirmed the shift-register
(HSPI 13/14 + latch 15), WS2812 (12), LDR (A0) and button pins, the
16-bit bit map and the tube order. The stock firmware has no I2C code
and drives a DFPlayer on UART0. Adds the ELF/xref helper tools.

Core/SDK version, flash layout, settings files and the hidden /d
hardware page whose Debug mode enables web OTA at /u.

Notes on the RetroModding IN-12 v2 clock (pinout, programming header,
plan for ESP_UniClock) and the maker's v2 schematic.
