/**
 * P-DTR public styles — ProfiRehab brand.
 *
 * These forms are embedded by shortcode into pages that already carry the
 * site's header, logo and branding, so nothing here tries to be a page. It
 * styles one component that has to sit calmly inside someone else's layout.
 *
 * The brief is a 35-field medical history, filled in by people who are in pain,
 * frequently on a phone, sometimes in one sitting and sometimes over days. Every
 * decision below serves legibility and a sense of progress over expression.
 *
 * Colour comes from the brand manual, with one correction it does not make:
 * #19ae70 against white is 2.9:1, which fails WCAG AA. So the primary green
 * fills shapes and never carries text on a light ground; #0d4c2f (10:1) is the
 * green that text is allowed to use.
