   ProjectRoots — Free-Canvas Family Tree Editor Styles
   ────────────────────────────────────────────────────────────────────────
   These styles only apply when a `#roots-canvas` element is present and
   pair with the editor JS in `tree.js`. Variables come from the parent
   `style.css` (--bg-color, --text-primary, --accent-primary, etc.) so
   the canvas inherits the site's light/dark/rainbow themes.
