/*
 * Frontend stylesheet for the CreaCaptcha widget.
 *
 * The <altcha-widget> custom element has no default block-flow spacing, so on
 * pages where the widget is visible (display="standard") and is the last child
 * of its parent form, the form's bottom edge sits flush against the widget.
 * Use padding-block-end rather than margin-block-end: padding does not
 * collapse with the parent's bottom edge, so the gap is always visible
 * regardless of whether the form has padding/border/min-height. Scoped to
 * display="standard" because floating/overlay/bar are positioned out-of-flow
 * and don't need block-flow spacing; invisible is display:none on the inner
 * .altcha anyway.
 *
 * The --altcha-color-base override binds the widget's primary colour to the
 * plugin's own --creationell-captcha-primary variable. The plugin emits an
 * inline <style> block setting that variable only when widget_primary_color is
 * configured; if unset, the var() fallback to the original --altcha-color-base
 * preserves the theme's default colour.
