dtourolle 8294e6b59f Call the reference curve what it is, and drop wording that reads as copying
The view transform's second curve is the DNG SDK's published reference
rendering — the ACR3 default curve applied by RefBaselineRGBTone — so
it is the "DNG Reference" curve in the panel, D21 and the code, not a
name borrowed from another product. Comments and docs that justified a
choice by another editor doing it ("as their Amount", "so a
photographer arriving from it finds the name") now give the actual
reason. The Vivid presets no longer describe themselves as reaching
for another editor's look; they are DarkRoom's own.

Factual mentions stay: which program wrote the library's DNGs, what
was measured against, and preset import. camera-profiles.md gains §15,
on starting a photograph from the edit it already carries.

# Vivid: more colour than the default rendering (camera-profiles.md §9).
#
# These do the work themselves, and work on every photograph — a JPEG, a body with no profile. 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.
