/**
 * WordPress 7.0 admin compatibility.
 *
 * WP 7.0 ships the "modern" admin redesign, which enlarges native form controls
 * (40px tall vs. 30/32px), reduces their corner radius (2px vs. 3/4px) and recolours
 * secondary buttons with a transparent fill and the modern accent (#3858E9). Our admin
 * UI was designed against the classic control metrics and the brand accent (#2271b1),
 * so the redesign throws our spacing and colours out of alignment.
 *
 * These rules restore the classic control metrics for native elements inside our admin
 * pages so the layout renders consistently on both WP 6.9 and WP 7.0. They deliberately
 * leave the admin menu, admin bar and `@wordpress/components` React widgets untouched —
 * only native inputs/buttons rendered inside our own markup are normalised.
