Ship a Vivid section of presets

Five looks for "more colourful than the default": Vivid, Vivid strong,
Vivid landscape, Vivid warm and Vivid portrait. They lean on vibrance,
which lifts muted colours most and holds skin back, and use saturation
sparingly on top; landscape and portrait work the colour mixer's bands
so foliage and sky get richer while skin does not. A sixth, Stronger
camera look, pushes the camera profile's look table to 175 %, about the
step from Adobe Standard to Adobe Vivid, and only moves vibrance where
a photograph has no profile.

All change only what they name, so they keep a corrected exposure or
white balance, and the shipped-preset tests bound every key and value.

+# Vivid: more colour than the default rendering, for the photographer used
+# to Lightroom's richer starting point (camera-profiles.md §9).
+#
+# Most of that difference is the camera profile's look table, which D20 now
+# applies where a profile exists. These go further, and work on every
+# photograph — a JPEG, a body with no profile — because they lean on
+# vibrance before saturation: vibrance lifts muted colours most and holds
+# skin back, so a frame gets richer before anything in it looks painted.
+# Saturation, which moves every colour alike, is used sparingly on top.
+#
+# Each changes only what it names (FR-DEV-6), so a corrected exposure or
+# white balance survives applying one.
