/*
 * nexus-forms estate look (1.9.1), loaded after the block stylesheet. The file name carries the version because the
 * Deflect edge keeps assets for years: a new look ships under a new name. Tokens only (the kit scope `.nxn`: --nx-*),
 * so light and dark come from the kit; the institution gradient (--nxi-grad) comes from the estate theme when the page
 * has one. 5px radius on every field, box and button; 44px controls; 24px minimum targets; a 2px focus ring; logical
 * properties only, so right-to-left pages mirror.
