/*
 * CourseFlow public enrollment (P5.3.1).
 *
 * - Every rule is scoped below .courseflow-enroll; nothing styles the page, headings, inputs or
 *   buttons outside it. Fonts, font sizes and text colour come from the theme.
 * - Colours and spacing are custom properties. A theme can set the public ones on any ancestor:
 *   --courseflow-accent (buttons, focus, current step), --courseflow-accent-text (text on the accent),
 *   --courseflow-radius, --courseflow-error. Neutral tints are mixed from the theme's text colour,
 *   so the component fits light and dark themes.
 * - Layout follows the width of the component (container queries), not of the screen, so it works in
 *   a full-width page, an Elementor column or a narrow content column. Below about 36rem everything is
 *   one column in source order.
