A drag tick requested the loupe's draft and the frame ended; the draft,
done in 1.5-3 ms on the GPU, was picked up at the start of the next frame,
a frame after the slider moved. Now, in a drag, the loupe waits up to 40 %
of a frame for its draft when the last loupe render took well under that
(not with a render offload, nor zoomed in, where what changes on screen is
the window's draft). A CPU render, which would only make the frame late, is
not waited for.
JobPool::wait waits for the next finished job, which try_recv then hands
out; Renderer::poll's collection of finished jobs is split out so the wait
can turn the draft into the texture.

The semibold family had a semibold Inter but, for other scripts, the same
regular craft-fonts faces as regular text, so a heading or the chosen tab
in Arabic was drawn at regular weight beside bold Latin.
A fallback face with a weight axis (today Noto Sans Arabic, 100 to 900)
is now registered a second time for the semibold family at weight 600,
through epaint's FontTweak::coords. The bytes are borrowed from the
embedded font, not copied. Faces with one fixed weight, regular and
monospace text, the order of fallbacks and Latin are unchanged.

With GPU rendering on and no graphics adapter at all (wgpu: "no GPU adapter among …", e.g. no
Vulkan loader: a `cargo run` outside `nix develop` on NixOS), every render ran on the CPU, much
slower, and only Settings ▸ Performance, Help ▸ System Info and `perf.gpuReason` said why.
The desktop app now queues one start-up notice per session once the device has been tried
(`gpu::ready()`, never blocking): "No graphics processor found: LightCraft renders on the CPU, which
is much slower. Details in Help → System Info.", on Linux with "On NixOS, start it from `nix
develop`." (→, not ▸: no installed font paints ▸.) `panels::notices::gpu_notice` decides from the
reason: nothing when the GPU was turned off (preference, LIGHTCRAFT_GPU, LIGHTCRAFT_GPU_BACKEND=off),
only a software adapter was skipped, or it failed later. Headless sessions and tests never show it
(`app.gpu_notice` is set by the desktop app only). Translated in all nine catalogs; one README
sentence in the Nix section.

Each drag tick changed the edited photo's settings, so the filmstrip asked
for a new thumbnail render every frame. For an unedited raw shown with its
embedded preview, the thumbnail-level source had never been decoded, so each
of those renders decoded the whole raw (a 64 MP ARW: over a second), several
side by side, and the loupe's drafts queued behind them.
- The edited photo's thumbnail is not re-rendered during a slider drag while
it has one; it follows once the drag ends.
- A thumbnail of a photo whose preview-level source is decoded (the one in
the loupe) is cut from that source (SourceRef::Fit) instead of decoding the
file again; not when the photo has a denoised picture.

The D90 writes 4352 x 2868 samples whose last 42 columns (from 4310) are
filler at a flat ~254, above its dark image samples (black 0). The
masked-column test only trims columns near zero, so they stayed in the
image and developed as a pink band on the right. Measured on 10 of 550
NEFs from one body: the camera's 4288 x 2848 JPEG sits at (10, 10), and
green saturates at 3840-3851 while red and blue run on to 4095, so one
white level of 3830 keeps clipped highlights white. The D90 joins the D4
in MEASURED_BODIES; other bodies are unchanged.

Sony ARWs of cameras without measured colour matrices were edited on the
relative scale (6500 K / 0 = as shot). Their SR2SubIFD stores the
multipliers of the camera's presets at 2500, 3200, 4500, 6000 and 8500 K;
lightcraft_raw::kelvin_presets reads the as-shot multipliers on the curve
through them and they take the spectral matrices' place in the #730
design (as-shot Kelvin and tint only; look, Bradford adaptation and the
pixel-identical legacy upgrade unchanged).
Covered: ILCA-99M2, ILCA-77M2, SLT-A33, DSC-RX10, ILCE-3500, ILCE-7S.
Kelvin-dial shots read back 3400 -> 3396, 5200 -> 5193, 4700 -> 4708,
5600 -> 5594 K; Shade 7493 K. Off-curve constants (isotherm tilt 0.74,
tint spacing 1) measured from the 14 Sony bodies with both spectral
matrices and presets.

Document polling of selection/settings/control ranges and shared edit
interactions. Clarify explicit-photo reads, empty selection and navigation,
and correct photo-tool ID descriptions and MCP initialization guidance.
Partial documentation work for issue 251;
hardware feedback remains outside this change.

Add correlated dark holdouts that reject misleading training and accept
matching training. Check finite, monotone curves in both cases. Confirm
the regression fails with the error gate removed and passes when restored.
Qualify the improvement claim when no original curve can be fitted, and
explain the source-look process policy and offline smart preview refresh.

Use separate luminance pairs for tone fitting so the camera look follows
its JPEG into deep shadows. Keep colour pairs and holdouts unchanged.
Require enough correlated shadow samples and lower held-out error, with
noise and compression floors and the existing median curve fit.
Add synthetic regressions, bump look and render cache versions, and
record the public multi-make and private numeric validation in the docs.
Fixes#1307
