- A segmenter that can't be built, with the model unreachable or a GPU
its delegate refuses, took the camera down with the pipeline: the SDK
fails the track it was attaching to, and the lobby muted camera and
microphone, on every load while the choice was kept.
- One is now built on trial when an effect is first wanted, before the
pipeline is attached to anything, on the CPU where the GPU refuses.
Where it can't be built, the options are disabled with the existing
notice for the rest of the session. The choice is kept: a browser
update may fix what failed.
- The view model takes that verdict from the pipeline's state rather than
asking the SDK, so both say the same, and it no longer builds a WebGL
context of its own to ask.
- Until the trial is over, the lobby opens no camera and the call makes no
camera track, so neither starts without the effect.

- The first effect chosen in a session shows a spinner on its own tile,
in place of the tick, until a frame carrying it is drawn. Later changes
show nothing, having nothing to prepare.
- Ended by the frame, not the promises, which resolve while the segmenter
is still being built. The transformer reports the first frame that went
through the segmenter; one passed through untouched doesn't count.
- The pipeline publishes the wait with its state, and both footer view
models take it as an input.
- The lobby tests' provider mock gains the observable hook, built once: a
fresh observable per render rebuilt the footer on every render.

- A catalogue of what can be chosen: no effect, blur, and two shipped
backgrounds, the app's own gradients flattened onto its canvas colour.
Their ids are what a saved choice stores, so they are named for the
pictures.
- One setting for the choice, typed as the ids an effect can have and
defaulting to blur for anyone who had it on. A stored value we no
longer ship, or one that isn't even a string, reads as no effect: it
comes from storage another build or a hand may have written.
- The pipeline follows it, switching in place to a picture as readily as
to blur, and the camera menu's blur toggle reads and writes it.
- So does Settings' blur checkbox: a picture reads as blur off, and
checking it replaces the picture with blur. The old on/off setting is
only read, to carry blur over. First tests for the Settings modal,
which fail with the checkbox on the old setting.
- The transformer's own init loads a picture chosen before it was built,
as the base init does and it had not: the first effect always is, and
the picture was drawn black.

- One pipeline, shared by the pre-join preview and the call, attached the
first time an effect is wanted and never detached after; turning blur
off switches it to a disabled mode in place. Main dropped the processor
whenever blur went off, and a pipeline taken off the camera is destroyed
and re-primed, so each time blur came back one unprocessed frame went
out. Built once, the priming frame is spent once.
- Still driven by the existing blur setting: nothing a user sees changes.
- Its logic is BackgroundEffects in src/state/, which the provider only
builds, so the tests drive it without rendering anything.
- Disabled drops the blur radius too. The SDK's disabled mode keeps it,
and with a radius every frame is still segmented and thrown away; with
neither a radius nor a picture, frames pass untouched.
- Switches run one at a time and skip any overtaken, so an earlier,
slower switch can't land after a later choice.
- Builds, rebuilds and teardowns of the pipeline run one at a time
(OneStepPipeline). The preview's and the call's tracks attach and stop
it independently, and the SDK's wrapper holds one track's streams: two
builds at once overwrite each other's, and a stop during a build does
nothing.
- Every camera track starts with the pipeline on: the room's capture
defaults follow it, and a camera turned off before the first effect is
replaced on turning it on, since a stopped track can't take one. One
attached after publishing lets the room through while it is built.
- BlurBackgroundTransformer becomes BackgroundEffectTransformer: it also
sits disabled, and its init applies that state as the SDK's would.
