Namespaces
namespace	PhosphorAnimation
namespace	PhosphorAnimation::detail

Concepts
concept	PhosphorAnimation::detail::PositionalGeometric
	Position-carrying T whose damage region is fully determined by endpoints + overshoot.
concept	PhosphorAnimation::detail::SizeGeometric
	Size-only T — caller must supply an anchor for damage rect.
concept	PhosphorAnimation::detail::ScalarValue

Enumerations
enum class	PhosphorAnimation::ColorSpace { PhosphorAnimation::Linear , PhosphorAnimation::OkLab }
	Interpolation space selector for AnimatedValue<QColor, ...>. More...

Functions
qreal	PhosphorAnimation::detail::srgbToLinear (qreal c)
qreal	PhosphorAnimation::detail::linearToSrgb (qreal c)
QColor	PhosphorAnimation::detail::lerpColorLinear (const QColor &from, const QColor &to, qreal t)
OkLab	PhosphorAnimation::detail::linearToOkLab (qreal r, qreal g, qreal bv)
void	PhosphorAnimation::detail::okLabToLinear (const OkLab &lab, qreal &r, qreal &g, qreal &bv)
QColor	PhosphorAnimation::detail::lerpColorOkLab (const QColor &from, const QColor &to, qreal t)
qreal	PhosphorAnimation::detail::colorDistance (const QColor &from, const QColor &to)
	L2 norm in linear-RGB space — matches the lerp space so velocity rescale uses a consistent metric.
DecomposedTransform	PhosphorAnimation::detail::decomposeTransform (const QTransform &t)
	QR-style decomposition on the 2x2 linear part under Qt's post-multiply row-vector convention: M = R x K x S.
QTransform	PhosphorAnimation::detail::recomposeTransform (const DecomposedTransform &d)
bool	PhosphorAnimation::detail::isPureTranslate (const QTransform &t)
	True if the 2x2 linear part is identity (only translation present).
QTransform	PhosphorAnimation::detail::lerpTransform (const QTransform &from, const QTransform &to, qreal t)

Variables
constexpr qreal	PhosphorAnimation::kRectSizeEpsilonPx = 1.0
	Sub-pixel epsilon for rect size-change detection.
