How themes work

Each theme is a set of CSS variable overrides for the board colors (paper, ink, selected, given, user-entered) plus an optional decoration layer with animated SVG elements (petals, ribbons, palm fronds, etc.). Your choice is stored in localStorage — no server round-trip, no account needed. Themes apply to every sudoku surface: daily, solo, race, co-op, and the per-difficulty landing pages.

On /sudoku/settings you’ll find the same picker with smaller previews, plus the page light/dark toggle (which is independent — you can run a dark page with a Paper board or vice versa).
