/**
 * PeptideLab — product buy box (swatches, quantity tiers, stepper, live total).
 *
 * Loaded only on single product pages, after woocommerce.css.
 *
 * Colour note: the reference design uses a blue accent. This theme already has
 * an established palette (navy + assay teal), so the selected states reuse
 * --pl-accent / --pl-accent-soft instead of introducing a second accent colour.
 * Swap those two variables below if you want the blue from the mockup.
