/*
 * Luccy CMS — neutral base styles of public dynamic forms (luccy-form__*, Luccy.Site.Core).
 * Plain CSS (no SCSS pipeline in Site.Core). Low specificity (:where) so a site restyles it with its own CSS or
 * replaces the wrapper partials (~/Views/Shared/DynamicForms/{SiteKey}/_X.cshtml). Theme through the custom
 * properties below. Half / third / two-thirds fields sit side by side in a 6-column grid and stack on narrow forms.
