The CYD restarted under load: a slider fill rounded less than its track made
LVGL draw the fill into a buffer of its own size on every redraw (15-20 KB), and
when that allocation failed the refresh retried until the task watchdog fired.
Track and fill now share one radius, and tests/test_layer_free.py keeps every
layer-making style out of the profiles, the packages and the firmware headers.
A tile keeps only the fields every card uses; climate modes, select options,
weather, sun and timer times, the media title and the vacuum rows moved to an
Extra block that exists only while a state needs one, and the state copy became
a fingerprint. runtime_tiles::model went from 24,296 to 8,216 bytes.
The manual profile that bound tiles to fixed entities in the YAML is gone:
331 TILE* substitutions, DYNAMIC_TILES/TILE_COUNT/DIRECT_ACTIONS, the 80 Home
Assistant subscriptions, its tap handlers and scripts, its own vacuum card, its
guides and helper scripts, and the five stale header copies in the repository
root that two C++ tests were compiling instead of the components. esphome config
of both Easy profiles is unchanged by that cleanup.
tile_scroll and the wake overlay no longer light up on a tap, and the debug
sensor min_free reports the lowest free heap since boot. On the bench CYD static
RAM went from 32.0% to 22.8% and free heap from 64-77 KB to about 101 KB, with
78 KB as the lowest point over thirteen hours without a restart.

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.
