/* ============================================================
   kf.css — the KidForms kit of parts
   ------------------------------------------------------------
   One shared file that holds every button, box, input and popup
   the site uses. Change a value here and it changes on every page.

   IMPORTANT: this matches how kidforms.co already looks. The values
   below were taken straight off the live signup page, landing page
   and app, so switching a page onto this kit should NOT change how
   it looks to a parent. That is the point: consistency now, and one
   place to make design changes later.

   Structure and naming follow the shadcn convention Lovable uses
   (primary / secondary / outline / ghost / destructive, and the
   background / foreground / muted token pairs), so the two builds
   speak the same language even though the look is ours.

   How to use it on a page:
     <link rel="stylesheet" href="/kf.css?v=3">
   Then delete that page's own copies of these rules. Page-specific
   styles go after the link, not before.
