/*
 * PHW Geräteausleihe gate - colour tokens from the PH Weingarten CD handbook.
 * The university website switches its theme via data-main-color="red|turquoise";
 * here both appear side by side, so each card carries its own accent.
 * Contrast (WCAG 2.2 AA): white on #e60f00 4.7:1, white on #007891 5.1:1,
 * #646464 on white 5.9:1. Highlight colours (#ff7d00, #00c2b0) are decorative only.
