/* HL7 Australia trainer registry.
 *
 * Brand values sampled from hl7.au: ink #0C0C0C, red #DA2128 for solid fills,
 * #EE2E24 for links, #C72026 for the darker shade, #F3F4F2 for panels.
 *
 * The red is a brand colour, not an interface colour. At roughly 4.1:1 on white
 * it fails WCAG AA for body text, so it is used for the logo, solid buttons and
 * focus rings — never for small text on a light background. Links take the darker
 * shade, and a lighter red returns in dark mode where contrast works the other way.
