/* ══════════════════════════════════════════════════════════════════════════
   NEW COMPONENTS: FAQ, Insights/articles, case studies, plans, tools.

   Conventions inherited from the blocks above: sections pad 5% horizontally,
   grids use auto-fit + minmax so they reflow without breakpoint micromanaging,
   and headings sit on --cyan with body copy on --text-muted.

   Fluid type via clamp() keeps these readable from 320px phones through to
   ultrawide without a stack of media queries. Interactive targets are kept at
   44px minimum for touch.
