/* HEAD SNIPPET ------------------------------------------------------------
   Meridian foundation - shared token sheet + classes (matches the React
   client token sheet so both apps render as one suite).

   Every template MUST add these exact lines inside its <head>:

   <link rel="preconnect" href="https://fonts.googleapis.com">
   <link rel="preconnect" href="https://fonts.gstatic.com" crossorigin>
   <link href="https://fonts.googleapis.com/css2?family=Cormorant+Garamond:ital,wght@0,400;0,500;0,600;1,400;1,500;1,600&family=IBM+Plex+Mono:wght@400;500;600&display=swap" rel="stylesheet">
   <link rel="stylesheet" href="{{ url_for('static', filename='meridian.css') }}">

   Pages that use window.mConfirm() (any page replacing window.confirm)
   additionally load the dialog helper:

   <script src="{{ url_for('static', filename='meridian.js') }}" defer></script>

   Notes for template authors:
   - Colors ONLY via the CSS variables below. No icon libraries; typographic
     glyphs only.
   - Cormorant Garamond (.m-serif) for display headings only; Helvetica stack
     for UI; IBM Plex Mono (.m-mono, tabular-nums) for money / times / counts /
     dates-as-digits / document numbers / emails-as-identifiers.
   - Radii: 2px controls, 3px cards. Circles only for avatars and status dots.
   - .m-topstrip is absolutely positioned: its parent needs
     position: relative (add overflow: hidden when the parent has a radius).
