    /* ── 700px — phones only: icon-kit cards go compact (icon beside the
       value) instead of shrinking the same stacked layout used at every
       larger width. :has() scopes this to grids that actually hold
       .stat-card-icon cards, so other .stats-grid users (admin, mentor
       accent-stripe cards) keep their existing 480px 1-column behavior
       untouched — :has() also gives this rule enough specificity to win
