 * Obliwise marketing site -- shared design system.
 *
 * Self-contained and CSP-safe: system font stack (no web fonts), no external
 * assets, inline SVG icons only. Served as static files by Express at /site/*;
 * each page also inlines a small critical-CSS block for instant above-the-fold
 * paint (LCP), then links this stylesheet for everything below the fold.
 *
 * Distinct from the utility app's index.css -- this is the sales surface, so
 * it carries its own (still restrained) marketing visual language. Builds on
 * the app brand: blue #2563eb primary, deep navy #0b1524.
