/* Connected '26 design tokens.
 *
 * Strategy: navy brand chrome (page background, header, footer) with LIGHT
 * working surfaces - cards, forms, and tables stay white for legibility.
 * Brand hexes from Mary Kate Hall (Slack, 2026-09-01). Two text contexts:
 * on-navy (page level) and on-surface (inside .card); tokens exist for both.
 * Contrast pairs are pinned by tests/test_contrast.py - change both together.
