/* Elegant Lists - Release A site stylesheet (WP-RA-CSS, OD-230).
   EL-U14 tokens as proposed (not approved branding until the owner's CSS OK).
   Plain CSS, mobile-first: no webfont, no at-rule except media, no url(), no
   script, no quoted string except an empty pseudo-element content. Every page
   stays complete and usable without this file (EL-U12). scanCSS refuses
   anything outside this dialect (OD-11 (b), Astra R4 B1). */
