Removing the composer puts it away rather than throws it out, and the way
back is one item in the band's menu — easy to miss on a page the composer
has just vacated. A mark flies from the control that removed it to that
menu, and the menu answers with one ring as the mark dissolves, so where
it went is witnessed rather than explained.
The cross and the menu item now read "Remove session chat", one name for
one thing whichever a reader reaches for.
Reduced motion skips both.

The rail and the drawer held two copies of the same column — the same
sections, in the same order, in two pieces of markup, so a change to one
silently skipped the other. Both now render `sidebarColumn`, and the
shells keep only what differs: the rail its width, resize handle and
collapse button, the panel its outside-click catcher and its transform.
A phone gets that panel rather than a modal. There was a width test
deciding between two presentations; the card under the band's handle works
at any width, so it goes. What is left of the width test is the choice
between a rail and a panel, plus a `(hover: hover)` test — the old
`innerWidth >= 768` was standing in for "has a pointer", which is what
decides whether the panel closes when the pointer leaves it.
With the card everywhere, the backdrop, the `aria-modal` (nothing dims and
nothing traps focus) and the drawer's close cross all go: the band's
handle opens the panel and a tap outside closes it. The burger row goes
with them. Entering panel width now collapses the rail transiently, so
coming back to a wide window does not land on a rail the page was resized
away from.
The band also stops easing its right edge. That transition belongs to the
rail, which moves the band's left; its right follows a splitter the page
owns, and easing it left the band lying over a session's side panel — a
blank strip across that panel's own header for 200ms after every drag.

Each of these kept a header of its own above the page. They register with
the band instead: the breadcrumb names what the page is on, and the page's
buttons sit at the far end of the one row.
They answer the band's width rather than the window's, since the buttons
share that row with the breadcrumb. The script editor folds Diff and
Settings into the menu it already shows when compact, the app editor drops
the panel buttons, Awareness and Export and goes icon-only on Deploy and
the mode switch, the flow editor menus its diff, and runs hides its
counters. Runs also declares `actionsFlexible`: its search is the one
control here that can give width back, and a box that refused to shrink
would make it take its maximum instead.
The run detail page loses its ActionRow, and the audit log its big title —
the breadcrumb says where you are, and the page keeps its tooltip.

The band publishes its width, so the pages filling it can answer it. Two
tiers: under 1000px the breadcrumb keeps the workspace disc and its env
badge and drops the name, and under PHONE_BAR (800) the trail stops
yielding at 10rem — that floor is what makes the bar wrap, so a page's
buttons take the line below rather than squeezing the name to an ellipsis.
The band also draws the line between itself and the page, and only while
something is scrolled under it. One capture listener on the window sees
every scroller, since most pages scroll inside their own box and never
move the layout's. An inset shadow, not a border: a border would move
every page down a pixel the moment the line appeared.
DetailPageLayout and InWorkspaceAppViewer drew that first line themselves;
two lines would stack, so theirs go.
