- test_nano: every hex digit of B data is one drawDots() call, never single
drawPixel() calls (the slow path that broke dense images in 2.19.2)
- tools/display_smoke_test.py: all yellow, a dense image and a checkerboard
in live mode on the real display; fails on any frame check problem (wrong
image, no answer, Nano restart, ERR reply)

Pages choose their own refresh effect (or the Hardware setting), used when
the page appears and for its own changes. Schedule blocks that switch
instantly and rules still switch instantly. The ESP32 sends page effects
to the Nano with a new no-save flag (E ...,2), so page switches don't wear
the Nano's EEPROM. Page format 7 (version 6 pages are converted).

The Nano's periodic full redraw blocked for ~0.8 s. A frame that arrived
meanwhile overflowed its 64-byte serial buffer; lost bytes in a bitmap
shift the rest of the image (picture moved up), and diff frames never
repaired it.
- Nano: all drawing (frames, effects, the dot refresh) runs from update()
in ~1 ms slices; the refresh pauses while a frame is received or shown
- New commands: C (reply with the image checksum) and I (refresh minutes,
EEPROM)
- ESP32: NanoMonitor asks for the checksum after frames and sends the whole
image again on a mismatch, missing answer or Nano restart; counts ERR
replies. Periodic whole-image resync.
- Settings: "Dot refresh" and "Image resync" intervals (settings v5,
v4 records are migrated)
- System tab: loop timing, free memory, frame check counts
- test_driver: the real driver against a simulated panel

Frames were sent as F0 plus one s command per yellow dot (thousands of
characters). During scrolling that overran the Nano's serial buffer, and
half-received frames redrew the whole screen. showBitmap() now sends two B
commands over the changed rectangle (dots off, dots on), or one B command for
a full frame, and the pacing counts the characters sent.

- Text elements can scroll in a window at a set speed; clock, countdown and
stopwatch can show seconds. Moving pages are sent as instant frames (new
Nano command D1) and paced by the estimated flip time.
- Countdown to a date and time (smart, days, days + time, with seconds),
stopwatch (web UI, HA switch and reset button), image element (fixed or
by Home Assistant state), multiplier for HA values, degree sign (char 127)
in all fonts and the font converter.
- Page format version 2; version 1 pages are converted.

Home Assistant: remove the Clock switch (its entity is deleted on connect),
add an IP sensor and Mode / Off image dropdowns whose options follow the
saved bitmaps. Remove the built-in "Nintendo border" bitmap.
Off image: a bitmap (or blank) left on the dots when the display switches off.
Nano: pause after each flip pulse and repeat pulses for changed dots, both
stored in EEPROM (G/N commands). Refresh effects (E command): instant,
sparkle, wipe, rain, from the middle out, diagonal, spiral, flip all then
reveal, push and random, optionally only for small changes. Effects run in
steps from loop() so serial input keeps flowing.
Web UI: flip settings, refresh effect and test patterns under Settings; the
System tab shows why the ESP32 last restarted. Settings records from
versions 1 and 2 are migrated. Firmware 2.3.0.

- New native environment: pio test -e native
- test/mocks: fake Arduino core, EEPROM and recording BROSE9323 driver
- test/test_nano: 25 tests covering every command, bitmaps, bad input,
flip time storage and the periodic full redraw
- Board environments ignore tests so they are never uploaded
