Divergence meter (Nixie tubes, world lines and clock), a D-mail sent
through the Phone Microwave using the panel's Message text, the Future
Gadget Lab inventory with live sensors, and a world line chart of today's
solar power. Original pixel art in tools/steins_sprites.py; the sprite
tool is shared between themes and Sprite, sprite(), polar() and arc()
move to el512_pages.h. HomeData gains the message and a 24 h solar
history in 15-minute slots.
The rotation now walks all pages in a random order that is reshuffled
every hour (Still Alive stays out, Now playing is skipped when idle).

Megumin's daily explosion, the Adventurers' Guild quest board (agenda,
weather, solar), Megumin's adventurer card and a party battle against a
giant toad with a live-data battle log. Original 1-bit pixel art lives in
tools/konosuba_sprites.py, which generates konosuba_sprites.h and can
render a preview PNG.
Home data and drawing helpers shared by the themed pages move to
el512_pages.h; the display gains dither_mask() for a dissolve-in intro.

Driver (components/el512/el512_panel.*, ESP-IDF only):
- DMA ring of 8 x 4 lines (17 KB) refilled from the I2S EOF interrupt
(IRAM) instead of a 142 KB full-frame stream; ~107 KB heap freed.
- 256-entry lookup table encodes 8 pixels per step.
- Back buffer + displayed buffer, swapped at the start of a frame.
- PlatformIO builds it via lib_extra_dirs (EL512Core); lib/EL512 keeps
the Adafruit GFX front end.
ESPHome external component (platform: el512):
- DisplayBuffer with optional ENABLE / _LOWPWR pins, set_enabled(),
set_low_power(), helper functions for page lambdas.
- still_alive_page: plays the Portal end-credits show, then returns to
the previous page.
Still Alive engine moved to components/el512/still_alive.* with a built-in
5x7 font (from Adafruit GFX, BSD); the PlatformIO demo uses the same code.
The importer writes components/el512/still_alive_data.h and stops at 200 s
(--until-ms), matching the hand-trimmed data.
esphome/el512-panel.yaml: 8 pages (clock, forecast, agenda, dashboard,
now playing, Plex, solar, Still Alive), page select, rotation, display
and low-power switches, message text. home_assistant/packages/el512_panel.yaml:
helper template sensors for forecast, agenda, now playing and Plex streams.

The source page splits some lines into several spans; a browser renders the
whitespace between them as a space, which the importer dropped ("becausewe").
It now adds that space. Regenerated imported.h.
Add a photo of the demo on the panel to the README.

Commit src/still_alive/imported.h instead of ignoring it. The importer now
writes a source reference (SDSkyKlouD/still-alive-web) and a disclaimer
(Jonathan Coulton / Valve, personal non-commercial use, not affiliated) at
the top of the file; the README carries the same disclaimer.

- src/still_alive: timed console text, typed scrolling credits and ASCII art,
laid out for 512x256 (41x31 console, 41x9 credits, 41x20 picture).
Plays placeholder content unless imported.h exists.
- tools/import_still_alive.py: generates the git-ignored imported.h (text,
timing, art, credits) from SDSkyKlouD/still-alive-web.
- platformio.ini: envs still_alive (default) and esp32dev (test images,
moved to src/test_images).
