The stopwatch counted with millis(), so it started at 0 after every
restart and would overflow after 49 days. It now keeps the real start
time (UTC ms) and the time counted before a pause, stored in NVS
(system/stopwatch_store) on every change, so it keeps counting while
the display is off or restarting. Stop pauses, Start continues, and the
Stopwatch tab can set the start to a date and time (local, summer time
by mktime) to count from, e.g. days since an event. Start, stop and set
need the synced time.
New page formats: 12d 4:05:09 and 3w 2d.
Version 2.19.0, tested on the display over OTA (set start, future and
invalid dates refused, pause, restart).

A new page element runs Conway's Game of Life in an area (the whole display
by default), one per page. Start: random dots, one pattern, or the icons
whose names start with a text in turn or in random order. Edges: wrap
around, dead, or a hidden margin where gliders fly out of view (leftovers
that stay put in the margin are cleared, so a glider gun runs cleanly).
It restarts when the board is still or repeats within 16 generations
and/or after a number of generations, after a hold time (an empty board
at once).
logic/life holds the board and timing (tested), display/life_player runs
the board of the shown page, ticked before each frame; frames are paced
like scrolling text. The element reuses existing fields, so the page
format stays the same. The Icons tab has a library of 17 LifeWiki
patterns (checked with a simulation), and the built-in page "Game of
Life" shuffles through the life_ icons. About 12 KB flash, 8 KB RAM.
Version 2.17.0, tested on the display over OTA.

The percentage (rounded down, in the element's font) is centred inside the
bar and its dots invert the bar, so it reads on the filled and the empty
part. It uses the bar's unused format and font fields, so the page format
stays the same. The Bad page shows it.

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).

- Home Assistant attributes can be paths into lists (forecast.1.condition).
- Date elements can show a day ahead (day offset 0-7).
- Pages hold 16 elements (page format 6; the old formats are frozen at 8).
Pages are reset in place (clearPage), not through a 4 KB temporary.
- Verwachting page: today (icon, temperature, max/min) and the next 2
days with 7 x 7 icons (weer7 <condition>), from a template sensor
(docs/home-assistant.md).
- examples/home-pages.json is exported from the display with all pages
and their icons, private entity id parts replaced by placeholders
(tools/export_examples.py replaces tools/make_example_pages.py).

Bitmaps that only pages use (backgrounds, images by state) are now icons:
own width and height, stored in /icons, not in the page lists or the Home
Assistant dropdowns. Page backgrounds and image elements use icons or
bitmaps; the renderer gets icons expanded at the top left, so pages look
the same. Web UI: Icons tab with an editor, Make icon / Make bitmap, Save
as icon on the Draw tab, icons in the backup.
A one-time migration in time-boxed steps moves the uploaded bitmaps that
only pages use, after the new firmware is marked good.

scroll_speed is now a float (0.05-30 dots per second, e.g. 0.25 = one dot
every 4 s). Page format 5; version 4 pages are converted, version 3 goes
through version 4.

- net/ha_api: the HTTP requests run in a FreeRTOS task on core 0; loop()
only hands over copies through queues. The web UI's test button polls.
No more 3-4 s loop() stalls once a minute; timeout raised to 5 s.
- Progress bar page element (page format 4, v3 pages are converted)
- Plex user setting (settings v6): {plex_user} in entity ids
- Plex page (examples): watchers, play/pause icon, title, progress
- Bitmaps cached in RAM: a LittleFS read took ~100 ms on every render
and web preview; long JSON lists sent in 2 KB pieces
- Backup includes the refresh settings and the Plex user

- Show as number (multiplier, decimals, auto unit W -> kW -> MW, without
minus sign), duration (seconds/minutes/hours as 2h 21m, 2:21:00, 2:21 or
smart), time (HA timestamps in local time, with weekday or date, or
relative: over 34 min / 12 min geleden) or own texts per state.
- Page format 3; version 2 pages are converted. Version 2.7.0.

- 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.

The hardcoded clock is now the built-in dynamic page "Clock". A dynamic page
has a background bitmap per time of day and up to 8 elements (clock, date,
Home Assistant value, text), each with position, alignment, font and overlay.
Pages are drawn on the ESP32, also for the web previews.
- Pages tab in the web UI: page editor with drag and drop, font upload
(TTF/OTF converted in the browser to the FDF1 dot font format)
- Built-in fonts Small, Normal, Large and Full height (generated by
tools/make_builtin_fonts.py), built-in bitmaps Pikachu and Pikachu yawning
- Home Assistant values over the REST API (URL and token in the HA tab)
- Settings version 4: evening settings removed (now time slots of the Clock
page), old records are converted
- HA Mode dropdown lists the dynamic pages and bitmaps
