SPA attach had no reconnect at all. Any dropped frame closed the socket,
`onClosed` fired, and the pane was destroyed permanently — the TUI
reconnects forever on the same endpoint. Session death also reached the UI
on two uncoordinated channels: the row from the events socket, the pane
from `ws.onclose`, with nothing reconciling them, so either could happen
without the other.
The catalog is now the authority. `shouldRetryClose` decides from session
status: Running means the link dropped, so retry with 500ms-to-10s
backoff; Dead means the PTY stream was sealed and nothing more is coming;
absent means it is gone. Application closes (4000+, a relayed daemon
rejection) and clean closes are never retried. The shell also closes any
pane whose session has left the catalog. The policy lives in reconnect.ts
so it is tested without a DOM.
kill_session checked `has()` before `kill()`, which only opened a window
for the liveness watcher to reap in between — turning a 404 into a 502.
`kill` reports the miss itself.
with_spawn_history logged and carried on when `Arc::get_mut` failed,
producing a daemon whose recent-dirs picker is permanently empty with
nothing to show for it. It panics now: that is a construction-order
mistake, at startup, in code that runs once.

Render the content pane as tabs of nested split trees, each session leaf a live
attach mounted through the multi-mount pool:
- #30 arbitrarily-nested H/V splits with mouse-resizable dividers; per-pane
⏻/▥/▤/✕ tools; closing a pane collapses its parent split.
- #31 tabs, each holding its own tree; add / switch / close.
- #32 drag-to-dock: drag a pane title or a sidebar session onto a pane for a
5-zone dock (edges split, centre swaps/replaces); a sidebar drag moves an
already-open session.
- #33 focused pane at full strength, others dim; sidebar shows focused (loud)
vs open-elsewhere (quiet) with a stable per-session colour mapping rows to
panes.
Opening a session fills the focused pane (single-pane parity by default);
multi-pane is opt-in via split / drag / tabs. Panes auto-close when their
session ends (guarded against eviction and intentional close). The steady
"connected" label is hidden as noise.
Closes#30, #31, #32, #33. Part of epic #37.

Rework the pool from single-active to a mounted-set model: several connections
can be visible at once (one per leaf), sessions no longer shown are parked
(still streaming) and bounded by an LRU buffer that never evicts visible panes.
Keep activate/parkActive/active() as compat shims and an onFocusChange/
onRequestClose surface; the HUD keeps working via active() -> focused().
main.ts now derives the single-pane view from a one-leaf layout tree via
setVisible/setFocus instead of calling activate directly — no behaviour change,
but the multi-mount path is now exercised end to end.
Refs #29 (epic #37).

Live-review iteration on the browser SPA, driven by crit feedback.
Sidebar / session tree
- Compact single-line leaf rows; status shown as a faint "alive" row wash
instead of per-row dots (exited rows dim + keep the "exited" badge).
- Host is now the first level of nesting (host → label path → session); the
inline @daemon is dropped from rows.
- Flush, borderless search input spanning the sidebar; drag-to-resize grip on
the sidebar edge (width persisted to localStorage); narrower default.
- Per-row clone action (opens the spawn modal prefilled); right-pointing
chevron when collapsed.
Chrome / layout
- Buttons swapped to a bracket terminal style ([ + Spawn ]); ghost/icon drop
the brackets. Old filled styles removed.
- Squared corners globally (radius tokens) and tighter, denser spacing.
- Session tally + daemon chips moved into the centered app header.
- Shorter control height; shared --bar-h aligns the search and attach bars.
Attach / terminal
- Useful attach title (name · command @ host) over a bare UUID.
- Robust fit: compute columns from the viewport's scrollbar-excluded
clientWidth (fixes mobile under-fit and desktop overflow); ResizeObserver +
font-load refit; full-bleed terminal on mobile.
Spawn / empty states
- Spawn modal accepts a prefill (clone); real "+ Spawn" buttons in welcome and
no-sessions empty states.
Dev
- New ?kit design-kit page (kit.ts/kit.css, DEV-only) showcasing components.
- Richer ?mock fixture with deeper label nesting.

Replace the full-screen route-swap SPA with a persistent two-pane layout:
- Global top bar (brand + Spawn + theme) above a sidebar (search + status +
session tree, highlights the active session) and a content pane (welcome or
the attached terminal). Selecting a row swaps only the content pane; the
sidebar and its store subscription persist.
- New `connections.ts` ConnectionPool: attach connections (terminal + WS) are
decoupled from the UI — navigating away parks a session (keeps it streaming)
rather than tearing it down, so switching back is instant with scrollback
intact. LRU-bounded (MAX_LIVE=6); explicit `⏻` disconnect distinct from nav.
- `attach.ts` → mountable `createAttachConnection`; `catalog.ts` exposes
`renderTopbar` + `renderSidebar`; `main.ts` is the shell + hash router.
- Responsive: desktop side-by-side; mobile single-pane (list ↔ terminal).
Single session viewed at a time (split panes deferred).
Typecheck + production build green.
