Interstellar: Gargantua with a time dilation clock (Earth today vs.
Miller's planet), TARS with his settings and remarks about the house,
the Endurance spinning at a solar-driven RPM while a Ranger docks, and
the tesseract's bookshelf with the time in binary dust and the Message's
first word in Morse on a watch.
Your Name: comet Tiamat splitting over Itomori's lake, and
kataware-doki, a countdown to sunset from sun.sun where two silhouettes
stand on the crater rim during the twilight hour.
HomeData gains sunset, sunrise and sun elevation (with an ISO time
parser); wrap() and typed() move to el512_pages.h. Share Tech Mono 22
gets the full Latin set. All pages are in the renderer, checked with
normal, busy and empty data.

LCARS ship status, the Cerritos duty roster from the agenda, a warp core
driven by solar power with Rutherford's advice, and a captain's log under
a viewscreen. Original pixel art in tools/trek_sprites.py.
When the 3D printer (Moonraker current_print_state, `printer`
substitution) is paused or in error, the panel jumps to LCARS Status in
red alert and holds the rotation until it carries on.

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.

Netrunner HUD, self-solving breach protocol, optics boot-and-scan and a
split HUD with a mini breach matrix, all in the page rotation. The el512
display gains animated_pages / animation_interval (redraw ~15 fps while
shown), page_age_ms() as animation clock, and shift_rows() / invert_rect()
for glitch effects.

The panel driver counts ring refills, the largest gap between refills,
frame swaps, swap timeouts and I2S TX FIFO underruns (takeStats()). The
ESPHome component checks them every 10 s and logs a warning only when the
ESP32 side of the signal had a problem, plus a debug summary per minute.
Measured with Wi-Fi on: ~4600 refills/s, max gap < 0.4 ms (lead 1.7 ms),
no underruns or timeouts, so remaining blinks come from the signal being
disturbed on the wires (Wi-Fi transmit bursts), not from the refresh.

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.
