   FastFlip — Component Styles (WordPress build)
   Generated from design-source/styles.css
   Modifications: removed mode/accent token blocks (Deep Blue
   tokens live in style.css :root), promoted [data-mode="black"]
   component rules to global since Deep Blue is the default mode,
   added WordPress-specific layout helpers at the bottom.
