/*
 * ReadPals layer over Ghost Source (loaded after built/screen.css).
 *
 * Tokens are copied from products/reading/marketing/src/app/globals.css; nav,
 * footer and prose mirror NavBar.tsx, Footer.tsx and Prose.tsx. No webfonts:
 * the marketing site uses the system rounded stack, and so does the blog.
 *
 * Readability deviations from the marketing tokens (WCAG AA 4.5:1 on cream):
 *   - article body text uses --rp-ink (12.9:1) instead of --rp-ink-soft (6.1:1);
 *   - secondary text uses --rp-ink-soft, never --rp-ink-muted (3.2:1);
 *   - links use --rp-link #167268 (5.4:1), a deeper --rp-teal-deep (3.8:1);
 *   - --rp-teal-wash is the site eyebrow wash (#D8F3EF) and --rp-sunny-soft the
 *     CTA card tint; only --rp-link / --rp-ink text sits on them;
 *   - the coral pill uses --rp-coral-ink #BF3B2B behind white text (5.4:1)
 *     instead of --rp-coral (2.8:1).
