/*
 * Visual style approximating the EBCOG (ebcog.eu) look — navy blue accents,
 * clean white cards, restrained clinical-society typography. This is a
 * best-effort visual match, not an exact copy of their stylesheet (that
 * wasn't something this plugin could pull automatically). Every color/font
 * is a CSS custom property below, so it's a one-block edit to match a
 * different site exactly if you have real brand values to plug in.
