/* ==========================================================================
   IS Solutions — Corporate Website
   Layout modelled on the Tabler (tabler.io) landing page:
   light-first, centered hero over a framed product preview, card grids,
   alternating split rows, accordion FAQ, gradient CTA band, column footer.

   Palette: enterprise indigo primary + teal/violet/amber data accents on a
   cool slate neutral ramp — readable, calm, and unmistakably "systems software".
   Dark theme is available via the toggle; light is the default.
