/* RT-qPCR Detection Chemistry Selector (SYBR Green vs TaqMan).
   Design tokens (var(--muted) etc.) come from the shared interactive-card.css.
   Scoped under #bsb-detection-chemistry so internals never leak.

   The source article used inline style="..." attributes on the container, labels
   and selects, plus inline colours on the JS-rendered result. Those styles are
   reproduced here as classes. */
