+// Every country poster used to carry the same hardcoded teal while each 100-list sheet carried its
+// own hue, which is the whole of the reported styling difference: a country sheet and a 100-list
+// sheet render through the SAME 253-line <style> block in poster-render.js and their stylesheets
+// are byte-identical except this one custom property. --zc drives the zone fill, the pin fill and
+// the pin-number background, the three most visible things on a sheet.
+//
+// ⚠ IT MUST BE DEFINED ONCE, FOR THE BROWSER AND THE NODE GENERATOR BOTH. Putting the rule in
+// generate.mjs alone broke check:poster-browser-equiv by exactly 26 bytes on country-npl -- the
+// length of 'hsl(45, 72%, 56%)' over '#2bb', twice, because --zc is emitted at two places. The
+// browser generates these sheets at click time from THIS module, so a rule the Node driver knows
+// and the browser does not is two different posters for the same country. generate.mjs imports
+// this; it does not keep a copy.
+//
+// The formula mirrors leafColor in the 100-list's legend-tree.js: an even hue spread at 72%/56%,
+// comma-HSL because Mapbox paint expressions reject the slash syntax. It is restated rather than
+// imported because library/ must not depend on plugin-designs/ -- the dependency runs the other
