The app could run a pipeline and had nowhere to keep what it was making. A
project is an ordered list of scenes, one JSON file each, and it is the only
part of the app that has to survive a reload.
A scene owns its prompt text and the result it produced, and nothing else. v4's
Scene grew three dozen fields; each belongs to the feature that needs it. Per
scene length and fps are deliberately absent — a regenerate uses the project's
values, so a scene cropped on the timeline comes back whole.
The prompt box edits the current scene rather than holding its own copy, so
what is on screen and what a run uses cannot disagree.
app: the region toggles are named buttons in the timeline bar
v4's arrangement. The kit's fallback is one glyph on a rail at each edge of the
window, which is right for a kit that cannot know what its panels are called and
wrong here, where they have names and a bar to put them in.
A pressed toggle was styled only inside a button group, so a standalone one
carried aria-pressed and looked identical either way.
gallery.strip is selectable like its siblings: a filmstrip is the one shape
whose whole job is saying which of these you are on.

v4's arrangement, which is the one that reads as an editor: a zone head
holds what acts on THAT zone, so the app grows a bar of its own for what
acts on the app.
* The menu bar. Brand, View and Settings, and whether ComfyUI is still on
the other end. Only menus with something real in them exist -- an empty
File menu is a promise the app does not keep.
* The prompt is written in the CONSTRUCTOR, a window. v4 called this the
Composer; that name is taken here by the element kit, and two things
called Composer in one repo is one thing nobody can search for. It is
the longest thing a person writes and the least often read, and a
permanent third of the centre column is the room the timeline needs.
The host is built at startup and outlives every opening, so a window
that opens twice does not throw away what was typed.
* The timeline replaces it, and Generate moves into its head with what
the run is doing at the far end of the same head. No bar across the
bottom: one that spans the window belongs to no region.
Four faults found on the way, three of them mine and one much older:
* THE OVERLAY ROOT WAS A STACKING CONTEXT. It documents at length that it
must never be one -- and then set `position: fixed`, which makes one on
its own. So the whole z ladder was measured inside that single element:
an open menu at z 500 painted UNDER a button at z 1. Every overlay in
the app was one positive z-index away from being buried, and the only
reason nobody had seen it is that almost nothing claims a z-index. The
root is static and zero-sized now; every layer in it is fixed already.
* Generate's hover ran `filter: brightness()`, which lightens the LABEL
along with the fill under it -- the one thing that had to stay readable
lost contrast in both themes. Only the fill moves now, and which way it
moves depends on the theme: dark's accent carries near-black text so it
goes lighter, light's carries white so it goes darker. Measured: no
gradient stop under 4.1:1, hovered or at rest.
* A fixed-height head could not shrink below the width of everything in
it, and a head now holds a title, three controls and a status. That
min-content became the centre column's, so a 768px window laid out
878px wide and scrolled sideways. It wraps now, as v4's does.
* A CSS patch of mine silently did nothing because its anchor text had
moved and I had left the assertion off that one replacement. Every
patch asserts now.
