/* Context Drift Heatmap: page-specific styles. Shared primitives live in ds.css, tools.css and ai-tools.css.
 * Heat cells mix the page material (--m) into --page-2 by a 0 to 80 percent share, so the lowest value is
 * the empty page colour and the highest is the material colour with dark ink printed on top. */
