<!--
The two halves of the Vaults tab: the tab itself, and the caret that opens its menu. Two buttons
because they do two things, drawn as one pill because they are one destination — so the pair meets in
the middle with no gap, no doubled border down the join, and the outer corners rounded as any tab's
are.
Both the Button and its ContentPresenter carry a CornerRadius above, so both have to be squared here:
setting only one leaves a rounded outline inside a square hit area, which shows as a hairline of the
strip's background cutting through the join.
After Button.tab.fixed rather than beside it, because .caret takes that rule's padding back to zero
and Avalonia has no specificity — the later declaration is the one that wins. See the ordering note
above.

One field. A team is made behind it and named after the vault, and its slug is derived — see
TeamsViewModel.CreateVaultAsync. Asking for a slug as the form above does would be asking for a

Two buttons drawn as one pill: the tab, and a caret that opens the vault menu. Split rather than
one button with a menu, because the tab's job is to go somewhere and that must stay a single
click — a tab you cannot press without being asked a question is not a tab.
── WHY A FLYOUT IS SAFE HERE, WHEN THE + BUTTON BELOW STILL REFUSES ONE ────────────────────────
That refusal stands and its reasoning is unchanged: this strip sits directly above the WebView's
rectangle, and whether a popup dropping into it composites above a native child window is not
something this project treats as settled without a screenshot.
What makes the question not arise here is the order in the handler. OnVaultMenuPressed selects
the Vaults tab *first*, which sets the shell's surface to a page and collapses the renderer — so
by the time the flyout opens there is no native child window under it. Exactly the move
QuickConnect already makes. It is also the behaviour a user expects: the caret belongs to the
Vaults tab, so pressing it going to Vaults is not a surprise.
The handler is explicit rather than Button.Flyout's own open, so that ordering is a thing the
code states and the headless suite can assert, rather than a thing the framework happens to do.
