/*
 * Shared nav arrow chrome — reused by:
 *   - `IPT_Hover_Image_Carousel_Widget` (carousel prev/next)
 *   - `IPT_Background_Slideshow_Widget` (slideshow prev/next when Show Arrows = on)
 *
 * The arrow is a 40×40 circular white button with a chevron SVG inside,
 * absolutely positioned to its container's vertical center and pulled
 * 12px in from the relevant edge. Mirrors the original carousel arrow
 * styling — the carousel's CSS used to host these rules verbatim; they
 * were extracted here so any new widget can opt into the same visual
 * language without re-implementing.
 *
 * Markup contract (rendered identically by both widgets):
 *
 *   <button class="ipt-nav-arrow ipt-nav-arrow--prev" aria-label="Previous">
 *     <svg viewBox="0 0 24 24"><polyline points="15 18 9 12 15 6"></polyline></svg>
 *   </button>
 *   <button class="ipt-nav-arrow ipt-nav-arrow--next" aria-label="Next">
 *     <svg viewBox="0 0 24 24"><polyline points="9 6 15 12 9 18"></polyline></svg>
 *   </button>
 *
 * The `!important`s are inherited from the original carousel CSS — they
 * exist to outrank theme button resets (Blocksy, Astra, Generatepress
 * all set their own `button` background / border). Removing them would
 * risk visual regressions on those themes.
