/* daddy-design-system — Landing / Marketing module
 *
 * Opt-in layer for public marketing pages (product landing sites). NOT part of the
 * core bundle: the core system is a calm operator control surface, while marketing
 * pages need a louder vertical rhythm, hero, and storytelling blocks. Link it
 * alongside the core bundle on a marketing page only:
 *
 *   <link rel="stylesheet" href="daddy-design-system.css">   (tokens + components)
 *   <link rel="stylesheet" href="landing.css">                (this file)
 *
 * Every class is prefixed `lp-` (landing page) to stay clear of the app shells.
 * Tokens only — no hard-coded hex; derive tints from a token with rgba(). Pairs
 * naturally with core components (`.btn .primary`, `.badge-accent`, layout utils).
 *
 * Sections, in document order: container · header · hero · works-with · standout ·
 * story · features · prose ("what it's not") · audience · split (hosted/OSS) · faq ·
 * cta · footer · responsive.
