/**
 * Stabilise the tech-specs Nivo slider height.
 *
 * The slides (frequency-response vs impulse charts) have different aspect
 * ratios, so Nivo resizes the slider between slides. Lock it to a single
 * aspect-ratio box and letterbox each chart with object-fit so nothing jumps.
 * Paired with assets/js/fix-tech-specs-slider.js (forces a fade transition).
 *
 * The white backdrop matters during the fade: without it, the letterbox is
 * transparent and the outgoing (taller) chart shows through the top/bottom
 * bands of the incoming (shorter) chart for a moment. A solid white backdrop —
 * which matches both charts' near-white background — turns that into a clean
 * cross-fade instead of a ghost frame.
