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.

- el512_panel.cpp: esp_cpu_get_cycle_count() exists only in ESP-IDF 5;
use cpu_hal_get_cycle_count() on 4.4 (Arduino 2.x), which broke both
PlatformIO environments.
- README: ring-buffer refresh, tear-free status, D1 mini ESP32, new layout
(components/el512, esphome/, home_assistant/), ESPHome setup, Still Alive
paths, and the Wi-Fi blanking findings with wiring advice.
- docs/README: ring, lookup table, double buffer, health counters; tear-free
and memory items done; Wi-Fi blanking and boot blanking as open items.

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.
