rows.css

/* rows.css: Work hub (redesign thread 3, Oct 2026). Loads after shared.css.
   The card itself comes from shared.css (wc-, ds-). This file adds the page
   around it: hero, groups, filter buttons, the deep dive inside a card, footer.
   Tokens only, so light and dark both work. Page classes start with wk-. */
