/* ============================================================================
   Imerwise · AI Tools — shared design system ("the theme")
   ----------------------------------------------------------------------------
   The single source of truth for the whole family. The hub uses it; every tool
   links it from the hub so one edit propagates:

       <link rel="stylesheet" href="https://imw-aitools.web.app/theme.css" />
       <script defer src="https://imw-aitools.web.app/theme.js"></script>

   A tool inherits ALL structural styling (neutrals, type, cards, buttons, chips,
   header, footer). It personalizes itself with exactly one variable:

       :root { --tool-accent: #a78bfa; --tool-accent-2: #818cf8; }

   Semantic colors (ok / warn) are shared and are NOT the accent.
