Dashboard sheet

A spreadsheet that reads like an Excel dashboard: each channel row carries an inline SVG trend sparkline and an eight-week heatmap shaded by volume. Total and Avg are live =SUM / =AVERAGE formulas - edit any weekly cell and the sparkline reshapes, the heatmap re-shades, and the totals update at once. Sparklines are a per-column custom cell; the heatmap is value-driven cellClass.
