/*
  Design plan
  Color: --bg cool grey surface, --card white panels, --ink/--muted text,
         --primary water blue (FilterDesk's own brand), --accent-light tint of primary,
         --success/--warning/--danger status states with soft tints for badges.
  Type:  Inter throughout — 700/800 for headings, 400/500 for body, tabular numbers for
         money/dates/schedules (this is operations software, numbers must line up).
  Layout: mobile-first single column; hero stacks art under copy; the product mock is a
          real app screen (tabs: mounter calendar / client portal), not an illustration.
