An alert from esp_screens_show_alert takes a `camera` (a camera.* or image.* entity): a Guition with firmware
0.2.57 shows that moment's picture across the top of the card, and a tap opens the camera full screen. A camera
or image tile opens the same full-screen view, refreshed every four seconds at a steady pace.
ESP Screen Manager fetches the snapshot with its own access, sizes it for the screen and serves a 24-bit BMP
under a random, short-lived link on port 8098; the screen loads it with ESPHome's online_image and holds no
Home Assistant token. BMP because ESPHome decodes it per chunk, where a full-screen JPEG held the loop 0.6 s.
The CYD keeps its alerts without the picture and gets no camera tiles.
The Guition also builds with ESPHome 2026.8+ again: backlight_fade.h derived from ESPHome's LEDC output, which
2026.8 made final, so the backlight now dims through ESPHome's own light transition.
Tested on the bench boards and a local add-on on the Home Assistant Yellow; docs/TEST_RESULTS_0266.md.

Wake from Home Assistant counted as a tap: it reset last_touch_ms, the one
clock that standby and Back to page 1 both read. An automation pressing Wake
on every motion therefore held an open card or page 2 up for as long as
someone moved in the room. Back to page 1 now has its own clock, last_use_ms,
written only by the boot, the touchscreen triggers, open_settings from Home
Assistant and the UI self test. Wake, an alert ending and Auto standby on
still restart the standby time, and Wake still brings back the brightness and
the second hand.
The rule moved from the interval into the script back_to_page_1_when_due.
Wake runs it right after waking a dimmed screen, so a page whose time ran out
during standby lights up on page 1 instead of jumping there a second later.
ESP Screens no longer opens the first screen by itself. Until one is picked
the page says "Choose a screen", and with no screens it still offers the
install; both cards start hidden so neither flashes while the page loads.
Checked with 48 host API checks per board, both ESP32 builds, 314 Python and
16 C++ tests, and the editor on the demo home. Firmware 0.2.56.

Dark mode is a new switch under Brightness on the screen's settings page, in
the Screen settings of ESP Screens and as switch.<screen>_dark_mode in Home
Assistant, so an automation can turn it on at bedtime. The screen changes
look at once, open cards and an alert included, and keeps it after a
restart. The design stays the same: a black page, graphite cards with a
hairline, soft white text, Home Assistant's state colours where they tell
something, and pastel card colours as deeper versions of themselves.
Every colour the firmware chooses now lives in components/smart_display/
theme.h: roles with a light and a dark value, the named card colours and
Home Assistant's state colours. The board profiles give widgets colourless
shared styles that theme.h fills, so a change of look refills those styles
and draws again what code painted by state. The light look is unchanged
apart from merges below one panel step. Dark mode costs 440 bytes of static
RAM on the CYD, and the LVGL tree of the host build is 416 bytes smaller; tests
keep colours out of every other file.
Comparing a screen that switched looks with one that booted in it also
found two older bugs, now fixed: a settings switch that was on showed its
knob at the left whenever its page was drawn, and the sun card's sunlit
area turned orange after a palette change. Firmware 0.2.54.

The README had grown into the full documentation. It now opens with a short
why, what and how, shows the screens and ESP Screens in pictures, and keeps
the installation steps. Every card, setting, alert and update detail moves
unchanged to README_EXTENDED.md.
The license now names Max Gramser; the README credits Adrian Kuehlewind's
ESPHome-touch-display-mount, where the first version started. The unused
background images from that project are gone.
