/* ---------- QUICK ACTIONS GRID (§4) ----------
   Round 4.1 update: horizontal compact layout — icon left, label/sub right.
   Saves ~60px vertical so stats + recent tables sit higher above the fold.
   Round 4.2 fix: scope h2 font-size — global `h2` is `--fs-h2` clamp up to
   4rem (64px) on wide viewports, default browser margin-block adds ~80px
   each → một tiêu đề ngốn 200px chiều cao. Đè về fs-md + 0 margin.
   Round 4.3 fix: HARD override section padding — base.css had global
   `section { padding-block: var(--space-2xl) }` ≈ 108px each side blowing
   up admin layout. !important here ensures cached old CSS can't win. */
