Theme Toggle Float

A single-word theme pill: the accent thumb crosses the track and drags the night layer behind it while the word rolls, letter by letter, from Light to Dark.

Celestial theme switcher — a porthole onto the sky: the night rises through it as a hard horizon, the sun sets below it and the moon rises out of it with the stars.

A two-word segmented theme control whose pill moves edge-first: its leading edge lunges to the other word and drags the night behind it, then the trailing edge follows and the pill snaps taut around the new label.

A terminal-styled theme switch with monospace status copy and persisted light and dark modes.
