   Notipa — Landing Page (notipa.org)
   Layered on top of app.css: same tokens (paper white / verified
   green / inventory ink), same type (Space Grotesk display + IBM
   Plex Sans body + IBM Plex Mono data), same component language
   (.btn, .tag, .card, .metric-tile, .page-header__eyebrow, etc.)
   as the product itself — this file only adds what a normal
   scrolling marketing page needs that the fixed app shell doesn't:
   a real document flow, a nav bar, a hero, page sections, and a
   footer. Nothing here overrides app.css's tokens or components,
   it only extends them.
   ============================================================ */

/* app.css sets html/body to height:100% + overflow:hidden, because
   the app itself is a fixed-viewport shell with its own internal
   scroll regions (.sidebar, .page-content). A marketing page is a
   normal scrolling document, so that's undone here. */
