/* ═══════════════════════════════════════════════════════════════════════════ SHARED TOP NAVIGATION — the single source of truth for the nav bar. ═══════════════════════════════════════════════════════════════════════════ WHY THIS FILE EXISTS (owner-reported 2026-07-25) The "Winning Predictions" dropdown rendered WHITE on /analyse and DARK on /, because index.html, analyse.html, team_dashboard.html and league_dashboard.html are each standalone documents with their own — and only some of them load iddaakolik-pro.css, which is where the navbar rules lived. Pages without it fell through to Bootstrap's default white dropdown. Bolting the whole 64KB pro.css onto the dashboards would have restyled far more than the nav, so the navbar rules are extracted here instead. Load THIS on every page that renders a navbar and the bar is identical everywhere. ── RULES FOR EDITING ────────────────────────────────────────────────────── * Change nav styling HERE, never in a page's inline
