Width, height and length belong to the PROJECT, not to a scene: a scene
cropped on the timeline and regenerated comes back at the project's size,
because the crop was a timeline decision and a regenerate is a new scene.
They sit in the Constructor beside the prompt -- the two things settled in
one sitting -- and travel to the graph on the path the prompt already uses.
No new mechanism: the pipeline declares roles at `project.video` the same
way it declares the prompt, so core still names no node and no setting. A
role whose value is a number gets a number control instead of a box; that
is the whole of the UI change. What the pipeline does not offer is not
shown, so a graph with no length input simply has no Length.
Bounds are the NODE's and stay there -- it already refuses a value outside
them with a reason, beside Generate. A project file is the one thing here
that outlives the code that wrote it, so everything read back out of one is
checked: a whole positive number, or gone.
Also, four faults the browser suite was already red with before this:
* Six tests still clicked a rail toggle that moved into the timeline head.
* At 420px the panel OVERLAYS the centre -- and the named toggles are in
the centre, so the panel covered the control that closes it. That is the
v4 trap this project forbids. They are not offered at that width now; the
View menu, which nothing can cover, is the way in and out.
* A 768px window laid out 860px wide and scrolled sideways. Root cause, and
it was never about one component: a flex item's automatic minimum is its
CONTENT, so every stack, split, panel body and frame region in the app
handed its content's width upward. A scroller that cannot shrink below
what it holds is not a scroller -- the strip of scenes made the WINDOW as
wide as the strip. Floored at the five places every layout routes through.
* A bin test counted `.cx-cell-glyph` across the whole page, so the timeline
drawing cells with the same glyph in them broke a test about the bin.
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.
