/*
 * REGE Membership — Form Stylesheet
 *
 * Follows the REGE design system exactly:
 *   Fonts:  Inter (headings) · Jost (UI/body)
 *   Radius: 4px everywhere
 *   Transitions: 150–300ms ease
 *   Content width: 620px max
 *
 * CSS custom properties mirror the WordPress theme variables so the form
 * inherits any future theme color updates automatically.
