/* Admin notices: stop the relocation jump.
 *
 * WordPress prints `admin_notices` BEFORE the screen opens its `.wrap`, so
 * every notice starts life above the heading. common.js then moves it on DOM
 * ready -- to `.wp-header-end`, or to the first h1/h2 when no marker exists.
 * The move is correct; the problem is that it is visible. On a heavy screen
 * the notice sits above the title long enough to read, then hops below it.
 *
 * So the notice is hidden while it is still in the pre-move position, and the
 * selector simply stops matching the moment WordPress relocates it into the
 * `.wrap` -- no second rule, no class toggling, no script of ours involved.
 *
 * THE :has() GUARD IS NOT DECORATION
 * ----------------------------------
 * The relocation only happens when there is a `.wrap` for common.js to move
 * the notice INTO. React-mounted screens (the Dashboard prints only
 * `<div id="mhm-rentiva-dashboard">`) have no `.wrap`, so their notices never
 * move -- and hiding one there would delete it permanently rather than defer
 * it. `:has(> .wrap)` scopes the rule to exactly the screens where a move is
 * coming.
 *
 * FAIL-SAFE
 * ---------
 * If the relocation never runs -- a JS error earlier on the page, a blocked
 * script -- the notice must not stay invisible; a licence warning nobody sees
 * is worse than one that jumps. The discrete animation restores it after two
 * seconds, which is far longer than a successful relocation takes and short
 * enough that the operator still gets the message.
 *
 * Only loaded on this plugin's own admin screens (AssetManager::enqueue_core_css,
 * behind is_rentiva_admin_page) -- other plugins' screens are none of our business.
