Uses attachCustomKeyEventHandler so xterm doesn't first consume Ctrl+V
and inject a raw ^V into the PTY. Paste routes through term.paste() so
broadcasting and bracketed paste continue to work.
Each leaf now carries an optional fontSizeOffset, persisted in
workspace.json alongside everything else. Ctrl+= / Ctrl+- / Ctrl+0
adjust the active pane; adding Shift escalates to every pane (the
mirror of the broadcast Shift+Alt convention, with shift alone since
the keys are otherwise unused). Bindings match on e.code so layouts
that don't have "=" / "-" / "0" in the same spot still work.
XtermPane gained a fontSize prop. A secondary effect reacts to changes:
set term.options.fontSize, fit() to recompute cols/rows for the new
cell size, refresh(), then resizePane so bash redraws the prompt at
the right width. No remount, so PTY + scrollback survive zoom changes.
The new tree helpers (resolveFontSize / adjustFontSize /
adjustAllFontSizes) are metadata-only — they don't swap leaf ids, so
nothing respawns. reshapeToPreset also carries the offset across when
splicing existing leaves into a new layout. 12 new vitest cases pin
those invariants plus the clamp and reset-to-default behaviour.

Most ResizeObserver firings in XtermPane don't change xterm's cell
grid — just shuffle a few pixels around. We were still calling
resizePane() (which SIGWINCHs bash, which redraws its prompt, which
emits data, which resets the idle timer). With many panes, this
created a self-reinforcing flap loop where the idle indicator would
toggle every few seconds.
Now: track the last cols/rows we actually sent to the backend in the
mount effect's closure. If a debounced fit() ends up at the same
grid dimensions, skip the resizePane call entirely. No SIGWINCH, no
prompt redraw, no data event, no idle flap.
Zero functional change for actual resizes; only suppresses redundant
PTY syscalls.

What the user saw: dragging a gutter filled the affected panes with
many overlapping bash prompts, some corrupted mid-print
(megaproxy@DESKTOP-megaproxy@DESKTOP-SSAQG5 etc).
Root cause: every resizePane() call sends SIGWINCH to the shell, which
makes bash redraw its prompt. The previous fix coalesced the local
xterm fit() into one per rAF, but still fired resizePane on every
rAF — 60+ SIGWINCHes per second during a drag, faster than bash can
finish one prompt redraw before the next interrupts it.
Fix: separate the two concerns. fit() + term.refresh() still run
every rAF (the visual must stay smooth). But resizePane() is
debounced to fire 150 ms after the LAST rAF — i.e. only when you
stop dragging — so bash gets one clean SIGWINCH at the final size
and produces a single tidy prompt redraw.

Two related fixes for stale glyphs / visual artifacts while dragging
a gutter:
- Gutter.tsx: pointermove now writes the new ratio into a ref and
schedules a single requestAnimationFrame flush per frame. Without
this, setTree fires 60+ times per second during a drag and React
+ ResizeObserver + xterm's DOM renderer get out of sync. The
pointerup handler flushes any pending ratio so the final position
always lands.
- XtermPane.tsx: the ResizeObserver callback now also rAF-coalesces
AND calls term.refresh(0, term.rows - 1) after fit.fit(). xterm's
DOM renderer doesn't reliably repaint freed-up rows after a
shrink, so the explicit refresh wipes any stale glyphs.

After hours of fighting Svelte 5's prop-reactivity through the
recursive Pane → SplitNode → LeafPane chain (props captured at
mount, never updated; context+getter pattern crashed; DOM-direct
workarounds created zombie-split click-intercept bugs), we
checkpointed the Svelte version (branch svelte-archive at e9015b2,
tarball at D:\archives\tiletopia-svelte-2026-05-22.tar.gz) and
rewrote the frontend in React.
Kept verbatim:
- All of src-tauri/ (Rust backend, Tauri config, icons)
- scripts/ (make-icon.py, release.sh)
- README.md, CLAUDE.md, memory.md
- src/lib/layout/tree.ts (pure TS — 43 tests still pass)
- src/ipc.ts (Tauri command wrappers)
Rewrote in React:
- src/App.tsx (top-level state via useState, OrchestrationProvider
for descendants via React.Context)
- src/lib/layout/orchestration.tsx (React Context API for shared
state — known-reliable reactivity, no Svelte 5 wall)
- src/lib/layout/Pane.tsx (recursive dispatcher)
- src/lib/layout/SplitNode.tsx (draggable gutter, local ratio state)
- src/lib/layout/LeafPane.tsx (toolbar + XtermPane)
- src/components/XtermPane.tsx (xterm.js wrapper, refs for callbacks)
- src/components/Notifications.tsx, Palette.tsx
Build: Vite + @vitejs/plugin-react. TypeScript strict. Same Tauri 2
config. Verified: pnpm check (clean), pnpm test (43/43 pass).
Not yet verified: pnpm tauri dev — that requires the Windows host.
