/* Color options preview (css/palette.css + js/palette.js): a "Try colors" button that lets the owners compare 5 palettes.
 * Each palette only swaps the color tokens from css/site.css :root ("Harmony Blue", their current brand, is the default
 * and lives there). Pick with the button or a link: ?palette=teal-trust.
 * WordPress build: a theme setting, on for the preview, off at launch (off = don't enqueue these two files; copy the
 * chosen palette's values into :root). Every pair is checked by tools/palette_contrast.py. */
