/*
 * nrs-api-pricing.css — 26th distinct flavor: monospace-quote-sheet.
 *
 * Visual language: cream printer paper, ink-blue ruled lines, a red
 * angled "QUOTE" stamp, IBM Plex Mono for body, Chakra Petch
 * for the headline, Familjen Grotesk for prose. The page reads like a
 * 1960s typed price sheet someone pulled out of a filing drawer.
 *
 * Strict project rules honoured:
 *   - WCAG AA 4.5:1 contrast on body text (#1f2a36 on #f4ede0 = ~10:1)
 *   - reuses the three project fonts only
 *   - no external assets, no images, no analytics
