/* ============================================================
   Korvia256 — shared site styles (v3)
   Used by every tool page. Keep this file generic; put
   tool-specific styling in that tool's own <style> block.

   IMPORTANT: bump the "?v=2" query string wherever this file is
   linked whenever you meaningfully change it, so returning
   visitors' browsers fetch the new version instead of a stale
   cached copy. e.g. <link rel="stylesheet" href="/assets/css/site.css?v=2">
