The dashboard needs: an animated funnel chart (sessions to orders) with the drop-off at every stage as a count and a percentage; KPI cards for revenue, orders, conversion rate, average order value and revenue per session, each with its change versus the previous four weeks; a channel comparison of conversion rate and revenue per session; a weekly trend chart with a metric switcher; a stage-by-week heatmap of step conversion rates that makes anomalies obvious, with any week where a step rate falls below 60 percent of its channel average flagged and explained; a what-if panel with sliders to lift each stage's conversion and see projected orders and revenue; filters by channel and week range that update everything; and hover or tap tooltips with exact values. Make it sharp, modern and executive-ready. So the page is alive without input, on load the funnel pours in stage by stage and a tour cycles forever: it switches channels on the funnel, steps through the weeks on the trend chart, flags the anomaly on the heatmap, and moves the what-if sliders to show the projection, until the user touches a control.

Save it as index.html in the current directory: one self-contained file with inline CSS and JavaScript only, no libraries or frameworks, and no external requests of any kind (no CDNs, web fonts, images or audio files). It must work when opened directly from disk, fit any window from a 390 px wide phone to a desktop, and run without console errors. You may serve it locally and open it in headless chromium (/usr/bin/chromium, software WebGL, no GPU) to screenshot and inspect your own output, and iterate on your own before finishing. Close any browser you open as soon as you've taken your screenshot.
