Move SFTP and S3 into the tab strip, and the host list into a card grid

Browse Source 
Four asks in one pass over the desktop head, and two of them are furniture
moving rather than anything new.

THE STRIP IS THE WINDOW'S NOW, not the terminal's. Vaults, SFTP and S3 sit at
its head and cannot be closed, and open terminals follow them. SFTP and S3 left
the nav rail to get there, which is the one semantic change: they are the two
destinations you stay in while something runs, and a rail entry is for
somewhere you go and come back from. So the rail belongs to the Vaults tab and
collapses with it, which also means SFTP, S3 and a terminal each get the full
1016 rather than the 826 a page gets.

The tab is expressed as "a page, and not one of the two the strip took" rather
than as a fourth ShellSurface. Both are still ShellScreen members and have to
be — that is what they are on the phone, where they are two rows in a hub — so
a surface each would have been a second way to say a thing Screen already says.
IsTransfersShowing and IsBucketsShowing light the other two tabs unchanged.
What is new is one field: the page Vaults comes back to, because it is the one
tab with sub-navigation and therefore the one that can return to the wrong
place. That is not the hidden field ShellSurface argues against — that one
would be a second copy of "which page"; this is a tab remembering its own.

THE HOSTS SCREEN IS A GRID, and the 268-pixel sidebar is gone. That column was
choosing among forty machines and editing one of them at two-thirds width, and
it was narrow so the editor beneath it could be a column at all. Cards took the
first job at full width; a 304-pixel drawer took the second and collapses when
nothing is selected. Pressing a group card narrows the grid; SHOW ALL is the
way back. The group editor moved into the drawer as well, which finally makes
IsEditingGroup mean the same thing on both heads — it was the phone's alone,
because the desktop's editor was a bar that was always on screen.

AreHostsExpanded and ToggleHosts went with the control that used them. They
folded the whole list away under one heading, an affordance that existed
because the column was narrow. Folding a single group is a different thing and
is still here.

THE TYPE SCALE IS A POINT LARGER and the text ramp is white. The base size was
never stated anywhere — a bare TextBlock took TextElement's default of 12 — so
raising the scale meant naming it, on Window and on UserControl. The second
selector is not redundancy: the layout harness hosts a UserControl in a window
it builds itself, and without it the suite would measure every screen a point
smaller than it ships, silently. A selector on TextBlock would have been the
obvious way and is wrong, because a style setter beats an inherited value and
would collapse every deliberate step back to one number.

#E3E7F4 is a blue-tinted white on blue-black surfaces, which costs contrast
twice — once for being darker than white and once for sharing a hue with what
it is drawn on. Pure white is 18.3:1 against the canvas where that was 15.5:1.
Every step below moved with the top, so the intervals the design chose are
kept and TextDim clears 9:1 against 6.4:1. The palette is shared, so the phone
has both changes too.

TWO DEFECTS THE HARNESS STRUCTURALLY CANNOT SEE, found by rendering the screen
rather than by measuring it, and both now covered.

The tile was 232 and was first written as 248, from arithmetic that left out
the scrolling stack's own margins. Every layout test passed — the harness asks
whether a control is inside the window, never how many fit on a line — so the
grid quietly became one column wide at exactly the minimum this application
guarantees, which is the shape cards exist to avoid.
TheHostsGridKeepsTwoColumnsAtTheMinimumWithTheDrawerOpen counts columns
instead, and fails at 248.

And a card's text ran past its own border, because a horizontal StackPanel
measures children with infinite width: a TextBlock inside one never learns it
is short of room, so TextTrimming never fires. Both card rows are grids with a
star column that gives way and an Auto column that does not — a hostname with
its tail cut is still the machine you were looking for, where a badge or the
word naming an auth method is not.

The keychain header changed shape for the same class of reason. It was
Auto,Auto,*,Auto with the buttons last, so the slack column was the only thing
absorbing a change of width and five buttons fell off the right edge the moment
the type grew. That is how GENERATE lost the word KEY once already. The summary
sits in the star column and trims now, so the buttons always get their width.

HostSidebarTests became HostGridTests and moved to the grid with the gestures
it drives. docs/design-import-gaps.md gains a v3 section naming the five
toolbar controls in the design with nothing behind them — a view-mode switch, a
tag filter, a calendar, a share control and Serial — and manual-checks.md and
the README follow the controls that moved.

Vaults, SFTP and S3 sit at the head of the strip and are always there. The name stays because the strip
is named in MainWindow, in the layout harness's height budget and in its own suite, and renaming a type
to track what it grew into is a rename across four files that leaves the product identical. What the
name now under-describes is written here instead.
── THE THREE FIXED TABS ─────────────────────────────────────────────────────────────────────────────
None of the three can be closed, and that is the difference between them and a terminal rather than a
styling choice. A terminal tab owns a shell and closing it ends that shell; these three own nothing —
they are three places this window goes, and a close box on one would be asking whether to destroy a
destination.
Vaults is first and is the only one with anything under it: the nav rail, and whichever of its screens
the rail points at. SFTP and S3 were rail entries until this strip existed, and they moved because they
are the two destinations you *stay in* while something runs. The rail is drawn only under Vaults; see
MainWindowViewModel.IsVaultsTab for why that is expressed as a page test rather than as a surface.
S3 carries no count although the rail entry it replaces did. There is room for one, and a number on two
of five tabs reads as a fact about those two rather than as the tab's own state — a terminal tab has
nothing to count, and the eye reads the strip left to right expecting the same shape.
── THE TERMINAL TABS ────────────────────────────────────────────────────────────────────────────────
Every one is one pane in the one WebView, so switching is a single frame telling the page which pane to
show — nothing is created, nothing is destroyed, and the shell behind a hidden pane goes on running and
goes on producing output. That is what makes tabs cost almost nothing here, and it is also why closing
one is the only thing in this application that deliberately ends a session.

Tabs became pills: taller, rounded, each with its own outline, on the sidebar's surface rather than the
chrome's. The design also puts a "Hosts" pill at the head of this strip and hides the sidebar while a
session is showing, so that pill is the only way back. This window keeps the sidebar up instead — it is
beside both surfaces rather than inside one — so the way back from a terminal is every destination at
once rather than a single pill leading to one of them. That makes the design's pill redundant, and a
redundant control on a strip this narrow is one the user has to rule out before finding the tabs.
