/* ==========================================================================
   GDI 5 — "institutional" skin (CEO 2026-11-03: "ma wyglądać jak poważna fundacja", side menu kept).
   Override layer on top of gdi2.css + gdi4.css. Layout, content and the left panel position are unchanged.
   What changes: a sober text serif for headings (Source Serif 4, SIL OFL, self-hosted), Inter stays for body;
   a deep-green institutional panel; one ink colour for headlines (no highlighted green words); document-like
   chapter rhythm (hairline rule + numbered kicker); no decorative watermarks, pills, "EST." badges or grids;
   partner/portal logos in one quiet tone until hover. Square geometry and hairlines as before.
