/* ============================================================
   /blood-testing bespoke catalog UI — blood-testing.html only.
   Scope: goal-hub cards, symptom filter, Top-12 panel grid,
   individual-test accordion + basket. CSS-only, zero DOM
   restructuring — symFilter()/btIndFilter()/btClearBasket() in
   this page's inline <script> query these exact class names and
   data-syms attributes, so every selector below is a stable
   contract, same discipline as css/book.css.

   The shared long-form content template below this UI (.va-page/
   .va-body/.va-table/.va-step/.va-faq, defined once in
   main.v3.css and used across many other pages) is deliberately
   NOT touched here — that's template work, sequenced later.

/* ── Responsive fixes ─────────────────────────────────────────────
   1. Modal form field pairs collapse to 1 column on phones (inline
      style can't hold a media query).
   2. Symptom filter chips are below the 44px touch target on mobile.
   3. Top-12 card CTAs use white-space:nowrap on longer labels — force
      a stacked, wrapping layout before that overflows 320px.
   4. .bt-basket is a second bottom-fixed bar; it sits flush to the
      viewport bottom (respecting the notch safe-area) and stays under
      z-index 470. The site-wide #vesey-mobile-bar is display:none at
      every breakpoint, so no 56px offset is needed to clear it. */
