 * Design direction: modern, clean, technology-forward; navy / white / restrained blue; high-end
 * commercial; lightweight and fast. The palette lives here as tokens in ONE auditable place
 * rather than as literals scattered through templates.
 *
 * No webfont is loaded. A system font stack renders instantly, costs no request and no layout
 * shift, and on this brief "lightweight and fast" is part of the design rather than a trade
 * against it.
