+# Skies: a bluer, deeper sky without touching the rest of the picture.
+#
+# Written against this pipeline, not derived from anybody's preset. Each
+# works the colour mixer's azure and blue bands — the hues a clear sky
+# occupies, 210° and 240° — darkening them and adding chroma, which is what
+# a polarising filter does to a sky and why it reads as "more blue" rather
+# than "more saturated". A grey sky has no hue for the bands to find, so on
+# an overcast frame these do little, by construction: they cannot invent a
+# sky, and a preset that tinted grey clouds blue would be one nobody trusted.
+#
+# Highlights come down with the sky in the stronger ones, because a darker
+# blue beside a clipped white cloud looks like a mask edge.
