Settings > Theme and Settings > Light or dark pick the colours of every screen (issue #10): roro9stack (the website's, the default), Catppuccin, Dracula, Nord, ANSI terminal, Gruvbox and Solarized. - A palette is 14 roles (lib/ui/src/palette.h). theme::kText and the others are now references into the one in use, so the Apps are unchanged; the main loop applies it when a Setting changes. - Every colour is one the RGB332 frame buffer holds exactly: the themes' own were rounded, and those that fell together or lost contrast were picked by hand. test_palette checks exactness and 18 contrast ratios for each palette. - The Sky view's constellation colours come from the theme. - `theme [0-6] [light|dark]` on the consoles.
