Look & Theme
Make the screen look the way you want
Two built-in themes β Ink Black (default) and Deep Blue β recolour the whole device in one tap. Five slots (background, top bar, panel, text, accent) are open for customisation, and a 24-swatch palette lets you pick colours on screen without typing a single hex value.
Every choice is written to NVS and restored after a power cut; switching themes triggers one full redraw so no leftover colour blocks stay behind.

- Custom colours are not contrast-checked β a very dark background with dark text becomes unreadable, so keep a clear difference between accent and background.
