Same page, two moods

Watch the theme sweep across the screen.

Flip the switch — the new theme expands outward from it using the View Transitions API, not a flat crossfade.

Native, not faked

The wipe is a real ::view-transition clip-path animation, not a full-screen overlay animating on top of the page.

Falls back gracefully

Browsers without View Transitions just swap the theme instantly — no missing functionality, only missing flair.

Remembers your pick

Your preference is saved, so a refresh keeps whichever mood you left it in.
