/* ── cascade-layer repair ───────────────────────────────────────────
   This file is unlayered; style.css (Tailwind v4) puts its utilities in a
   layer. Unlayered normal declarations always win over layered ones, so the
   base utilities above (.w-full, .flex-col, .items-end …) silently outranked
   every responsive override in style.css — .lg\:w-auto could never beat
   .w-full. That collapsed the classic rate-board header to zero width and
   mis-sized the chart canvas. Re-assert those overrides here, after the bases
   they need to beat, with theme vars resolved so the rules stand alone.
