/* Cyopsys portal — dark brand theme.
 * Brand DNA from the original Salient build: accent #3452ff, gradient
 * #062d62→#107fa8, dark surfaces #1f1f1f/#313233. On dark backgrounds the
 * raw accent fails AAA for text, so text roles use lightened tints; the
 * raw accent carries buttons with large bold text only.
 * Contrast pairs verified ≥7:1 (WCAG 2.1 AAA) by tests/test_cyportal.py.
