With Bypass Linear Light Conversion off, Exposure decoded and re-encoded
with the piecewise sRGB curve. After Effects 2026 renders (sRGB working
space, 32 bpc) of Offset 0.0005 / 0.002 / 0.02 / 0.1 on black measure
8 / 15 / 43 / 90, which a pure 2.2 power predicts (8.06 / 15.13 / 43.08 /
89.54) and the sRGB curve does not (1.65 / 6.59 / 38.68 / 89.04).
The effect now uses its own 2.2 power curve on the CPU and in the GPU
kernel; the shared colour functions and other effects are unchanged. As
before, the conversion applies whatever the working space, also a
linearised one. Negative values go through both curves mirrored (input
was clamped at 0 before), so defaults are an identity for 32-bpc values
and a negative Offset darkens past black without NaN.
New test against the AE values; existing Exposure tests still hold.

After Effects tints Black & White's gray like a Color blend: the tint colour's
hue and saturation at the gray's luminosity (weights 0.3 / 0.59 / 0.11, channels
outside 0..1 pulled back toward the gray). EffectCraft used the gray as HSL
lightness. Measured in AE 2026, Tint Color [1, 0.5, 0]: a red solid at Reds 10
(case 717) AE (43, 21, 0), EffectCraft was (51, 26, 0), now (43, 21, 0); a
yellow solid at the default sliders (gray 0.6, case 825) AE (255, 129, 2), now
(255, 129, 3); white stays white. The six sliders already matched AE on eight
colours (cases 816, 817). CPU and GPU.

After Effects' Tritone weighs the working-space values with Rec. 601 (0.299,
0.587, 0.114), as its Tint does; EffectCraft used Rec. 709. Case 718 (red solid,
Highlights [1,1,0.8], Midtones [0.6,0.2,0.2], Shadows [0,0,0.3], Blend 25):
AE (132, 23, 46), EffectCraft was (113, 16, 49), now (132, 23, 46). On a grey
ramp (case 815) the shadows / midtones / highlights mapping already matched and
still does within 1/255. CPU and GPU (fx_color op 4).

After Effects 2026 (sRGB working space, not linearised) maps red, green,
blue and 50% grey solids at Tint's defaults to 76, 150, 29 and 128/255:
Rec. 601 weights on the working-space values, not Rec. 709. CPU and GPU
kernel changed; tests pin the four greys within 1/255.

- render --progress with a piped stderr writes well-formed
`progress <done> <total> <elapsed> <left|->` lines, one per change, and
the same render without the flag writes none.
- A template's Media Replacement control takes {"path"|"file"|"media": …},
is found by name ignoring case, and a path that cannot be imported fails
with an error naming the control and the path.
