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.

App 0.2.47 / firmware 0.2.40:
- guition-4848s040.yaml gets the CYD's climate card: the setpoint between large -/+ keys
(debounced, hold to repeat) and one row of mode keys in HA's order and colours; the arc,
scrim, mode pill and climate_number font are gone.
- Fan and swing modes sit right on the card as segmented rows behind their icons, drawn by the
new climate_card.h (async rebuild, taps through the touch guard and a profile hook). The card
is laid out per case from one table: no, one or two settings rows, with or without mode keys.
- Both boards hide a mode key row that would hold a single mode and centre the setpoint instead.
- Glyph arrow-oscillating (Home Assistant's swing icon) joins the icon set.
Verified on the Guition over OTA with the owner's air conditioner and with host renders of both
boards; see docs/TEST_RESULTS_0247.md.
