/* Shared A/B comparison row component.
   Used on /demos (dark default) and product pages /foxfire and /autocatalysis
   (add `.is-light` modifier for the cream theme).

   Multi-take rows use `.ab-toggle button[data-src]` for Dry / Wet 1 / Wet 2.
   Single-take rows omit `.ab-toggle` and put `data-src` on the row itself --
   layout collapses to 4 columns and the take-caption row is hidden. */
