/* Postling — postling.app
   Layout: one long page on warm envelope paper; a two-column hero (promise + example briefing, franked
   with a postmark), then bands for the noise, how it works, features, a dark-green privacy band,
   audiences, pricing, FAQ and the beta form. Coral is the stamp, green is the stamp's ground. */
