Cause: pipeline::Cx rendered with Backend::Auto, which picks the CPU or the
GPU compositor for each top-level frame from measured frame times
(render::AutoPick: warm-up on both sides, a re-probe every 48 frames). The
two compositors differ slightly, so frames came out differently depending
on which side the timings favoured in that run, and two GPU exports of the
same frames differed.
Fix: the job renders every frame on the project's renderer, as After
Effects renders a job with one renderer: Backend::Gpu with Mercury GPU
Acceleration (frames the GPU declines still render on the CPU, as they do
in every GPU render), Backend::Cpu with Mercury Software Only. The viewer
and previews keep Auto. Docs (architecture, parity, web) say so.
Tests: render_settings::a_job_renders_on_one_compositor exports ten frames
with a stand-in GPU compositor that keeps Auto history and draws solid
green: with Mercury GPU Acceleration every frame is green and two runs are
identical (with Auto the warm-up sent frames to the CPU: it fails), with
Software Only the stand-in is never asked. The web worker GPU job test's
comment no longer describes Auto.

Keep serving during long renders, recover failed workers, and remove only files opened by the interrupted export. Cover progress, cancellation, EOF and output ownership with regression tests.

The Output Module offers 32 Bit Float for AIFF and the queue reports F32, but
audio_file silently wrote 24-bit PCM because plain AIFF has no float. Write
an AIFF-C file instead: FORM type AIFC, an FVER chunk (AIFC Version 1), and a
COMM chunk naming the fl32 compression type, with big-endian IEEE float
samples in SSND. 16- and 24-bit stay plain AIFF.

Render Settings: field render with 3:2 pulldown phases, effects/solo/guide
layer/color depth/frame blending/motion blur overrides, custom time sampling
(duration), storage overflow through a quota hook. Output Module: crop
(edges or region of interest), resize (presets, lock aspect, quality),
straight/premultiplied/alpha-only channels, post-render actions, include
project link, audio channels and PCM formats, WebM bitrate and key frame
interval. Render Settings / Output Module templates with built-ins and
defaults per slot (Edit > Templates dialogs), render logs next to the
output, Notify on completion. All through renderQueue.* commands and
persisted in the project.
