 * kody-search — minimal frontend CSS
 *
 * Mostly structural: dropdown positioning, spinner, z-index. Typography
 * inherits from the active theme. A handful of rules set sensible
 * defaults so the widget doesn't look broken on themes with minimal
 * base styles (result highlighting, focus ring, dropdown elevation) —
 * these use CSS4 system color keywords (Canvas, Mark, Highlight, etc.)
 * so they adapt to the browser/OS theme instead of hardcoding a brand
 * color, keeping the "no color pickers" design intact.

	 * Forces a proper stacking context onto the widget's own subtree. Without this,
	 * the inline widget's <input> can render on top of an unrelated, taller,
	 * absolutely-positioned overlay elsewhere on the page that geometrically
	 * extends over it — reproduced with WooCommerce/Storefront's mini-cart flyout:
	 * a thin line from the input painted straight through the flyout's contents,
	 * despite the flyout's z-index (999999) being nowhere near ours (we set none)
	 * and its background being fully opaque. `position: relative` with the z-index
	 * left at auto is not enough to stop this — it does not by itself establish a
	 * stacking context, so the browser is left to reconcile the two elements'
	 * compositing layers on its own, and does so incorrectly in this case.
	 * `isolation: isolate` is the standard fix: it forces exactly the stacking
	 * context `position: relative` alone does not, with no side effect on layout.
	 *
	 * This is only about the <input> vs a foreign overlay. The results dropdown is
	 * the other direction — it must escape *this* subtree, not be contained by it —
	 * and does so via the Popover API top layer (see .kody-search-results-wrapper
	 * below), which is unaffected by this stacking context either way.
