Every screen gets the user action esphome.<device>_show_alert with title,
subtitle, icon, color, button_text, timeout and flash. The card sits on
LVGL's top layer above every page, card and the dim overlay, wakes the
screen and keeps the backlight at its normal brightness until the button
(or the timeout; 0 waits for the button, the button always closes at
once). flash: true blinks the backlight four times on arrival. Icons are
the tile picker names (also mdi:name or the hex codepoint of a compiled
glyph, else alert-outline), colours the tile pastels. A new alert replaces
the current one; every ending fires esphome.screen_alert with action,
title and screen. dismiss_alert removes the card remotely.
The field is button_text rather than button: ESPHome reserves the names
of loaded components as ids and the CYD profile loads button:. The C++
namespace is screen_alert because the widget id alert_overlay becomes a
global lv_obj_t*.
tools/generate_icons.py now also writes tile_icon_names.h (name to
codepoint) from the one icon list. Firmware 0.2.31 for both boards.

Large-value (watch) tiles show a small domain icon next to the title, centre
title and value vertically, use a dedicated larger digit font, truncate long
values with dots and keep the unit in its own label. The geometry self-test
checks the unit label too.
The Guition backlight now dims through the LEDC hardware fader (1.5 s to
standby, 80 ms wake) so full LVGL redraws no longer make the transition
stutter; ESPHome's light state is synced after each fade. Firmware 0.2.13;
app 0.2.11 stays compatible. Document the shared build directory pitfall.
