  contains the small set of rules Tailwind utilities
  can't express.)
==================================================*/

/* ===================== Base ===================== */

html {
    scroll-behavior: smooth;
}

body {
    overflow-x: hidden;
}

::selection {
    background-color: #0A6EBD;
    color: #ffffff;
}

/* ===================== Scrollbar ===================== */

::-webkit-scrollbar {
    width: 10px;
}

::-webkit-scrollbar-track {
    background: #F8FAFC;
}

::-webkit-scrollbar-thumb {
    background: #0A6EBD;
    border-radius: 999px;
}

::-webkit-scrollbar-thumb:hover {
    background: #075a99;
}

/* ===================== Header ===================== */

/* No background-color rule here on purpose: the header is
   transparent by default (no bg-* class in the HTML) and
   script.js adds Tailwind's "bg-white shadow-lg" classes on
   scroll. An ID selector here would out-rank those utility
   classes and permanently force the header transparent. */

#header {
    transition: background-color 0.4s ease, box-shadow 0.4s ease, padding 0.4s ease;
}

#header.scrolled {
    backdrop-filter: saturate(180%) blur(8px);
