/* ==========================================================================
   SmartBooks — product page
   Single stylesheet, no build step. Dark cyber edition: this page now wears
   the same design system as smartpro.ae — deep-space canvas, cyan→violet
   neon, Space Grotesk display, JetBrains Mono technical accents. The
   SmartBooks purple/amber survives as the product's own accent inside it
   (the note rules and the app-window bar), sampled from logo-full.png.

   Fonts load from Google Fonts and degrade gracefully to system fonts when
   offline — the page still works from a USB stick with no internet.
