/* Survey themes -------------------------------------------------------------
   A theme overrides the colour tokens above; everything else (radii, layout,
   the submit button's green) stays shared. The fixed list lives in
   src/lib/theme.ts and the server validates every value before it is stored.

   `data-theme` is set on <html> for the public form, on the builder's preview
   pane for live previews, and on the picker's swatches — the selector is
   intentionally not tied to :root so all three keep working.

   `--ink` must stay readable on `--bg`/`--card` and `--accent-ink` on
   `--accent`; keep new themes at WCAG AA for body text. */
