The global button transition and the :active scale(0.97) transform were
interfering with the translateY(-50%) centering, making the buttons jump
on press. Added transition:none and reduced :active to translateY(-50%)
only (no scale).

Mobile Safari (iOS) blocks requestFullscreen() on non-video elements,
so the Fullscreen button silently did nothing.
Add a CSS-based fake fullscreen path:
- mapEnterFakeFullscreen() adds .map-fake-fullscreen to #map-stage
(position:fixed; inset:0; z-index:9000; height:100dvh) and
map-fake-fullscreen-active to <body> (overflow:hidden).
- toggleMapFullscreen() tries native fullscreen first; catches the
thrown NotAllowedError (or any other error) and falls back to the
CSS path. Also handles the case where requestFullscreen is absent.
- mapIsFullscreen() checks for the CSS class in addition to the
native fullscreen element references.
- mapExitFakeFullscreen() removes both classes on exit.
- Escape key exits CSS fake fullscreen (native handles its own Escape).
- sizeAprsMapToViewport() uses window.innerHeight for the fake path
since clientHeight may not reflect fixed layout synchronously.
- sizeAprsMapToViewport() is called via requestAnimationFrame after
toggling so layout is settled before the Leaflet invalidateSize().

Two bugs fixed:
1. Wrong vertical position of shift buttons and bookmark side panels.
top: calc((--spectrum-plot-height - --overview-plot-height) / 2)
evaluates to 0 when both vars are equal (default 160 px), so
translateY(-50%) placed the buttons at the top edge of .spectrum-wrap
instead of mid-canvas. Changed to calc(--spectrum-plot-height / 2).
2. Rapid clicks on the arrows did not accumulate: each call read
lastSpectrumData.center_hz which is only updated when the server
sends a new spectrum frame. Added spectrumCenterPendingHz to track
the optimistic center immediately on click; reset when the server
confirms a frame near the expected position.
Also hide .spectrum-bookmark-side on ≤640px (no horizontal room on
narrow phones); previously visible but clipped off-screen.

Move history replay out of the /decode SSE stream into a new
GET /decode/history JSON endpoint. The JS client now opens /decode
immediately for live packets (no gating) and fetches history in
parallel via fetch(), draining it in the background with the existing
chunked drainDecodeHistory() helper.
This ensures real-time decode messages are never blocked by a large
history payload, and removes the historyReceived gate entirely.

Previously the server emitted N individual SSE events (one per decoded
message) followed by a history_done sentinel. With a 1.3 MB history
this caused thousands of EventSource onmessage callbacks each blocking
the JS main thread, interrupting audio playback and spectrum rendering
for 50+ seconds.
Server: serialize the entire history Vec as a single named "history"
event containing a JSON array, then chain directly into the live
decode stream. One serde_json::to_string call instead of N.
JS: listen for the "history" event, parse the array once, pass it to
the existing drainDecodeHistory() chunked dispatcher (30 msgs per
setTimeout slice to stay off the main thread), then gate onmessage
dispatching on historyReceived. Removes the historyBuffer accumulator
and the history_done event entirely.

Chrome classifies wheel events as "pointer" interactions and tracks async
continuations initiated by the handler. The wheel-on-freq-input path was:
jogFreq → setRigFrequency → postPath(/set_freq) [~700ms]
→ ensureTunedBandwidthCoverage [~700ms]
...two sequential network round-trips totalling ~1400ms of INP.
Three changes:
1. yieldToMain(): add a scheduler.yield() / setTimeout(0) helper that
yields the main thread back to the browser. Chrome's INP interaction
tracking ends at the yield point, so the network RTT no longer counts.
2. jogFreq: call applyLocalTunedFrequency() optimistically before the
yield so the freq display updates are visible in the very next paint,
then yield before firing any network requests.
3. setRigFrequency: move applyLocalTunedFrequency() before the awaits
(consistent optimistic-update contract for all callers), and run
postPath(/set_freq) and ensureTunedBandwidthCoverage() in parallel
via Promise.all — they are independent server operations.

Replace Arc<Mutex<SharedSpectrum>> with Arc<watch::Sender<SharedSpectrum>>
throughout the stack:
- SharedSpectrum: remove revision counter, derive Clone, make fields pub,
rename replace() → set(). The watch channel handles dedup natively.
- FrontendRuntimeContext.spectrum: Mutex → watch::Sender; SSE clients
call .subscribe() to get a push-based receiver at zero polling cost.
- RemoteClientConfig: derive Clone, switch spectrum field to match.
Spectrum polling moves to a dedicated TCP connection (run_spectrum_connection
+ handle_spectrum_connection spawned as a separate tokio task). This
eliminates head-of-line blocking: spectrum timeouts no longer stall state
polls or user commands on the main connection. Each side reconnects
independently; the spectrum task marks the frame None while reconnecting.

State deduplication via PartialEq + send_if_modified:
Derive PartialEq on the full RigState / RigSnapshot type tree
(Freq, Band, RigInfo, RigCapabilities, RigStatus, RigTxStatus,
RigRxStatus, RigControl, RigVfo, RigVfoEntry, RigFilterState,
RdsData, SpectrumData, RigState, RigSnapshot). Use
state_tx.send_if_modified() in refresh_remote_snapshot() so
WatchStream only wakes SSE /events subscribers when state
actually changed; with a stable rig this eliminates ~1.3
spurious JSON serialisations per second per connected client.
Cache-remote-rigs skip on unchanged list:
cache_remote_rigs() was rebuilding the Vec and cloning every
field on every 750 ms poll. Add a structural check (rig_id,
display_name, initialized, audio_port) and return early when
nothing has changed — the common steady-state case.
RDS JSON pre-serialised at ingestion:
SharedSpectrum.replace() now serialises the optional RDS object
once and stores it alongside the Arc<SpectrumData> frame.
Each /spectrum SSE client's 40 ms tick reads the cached string
instead of calling serde_json::to_string() per-client per-tick.
Add serde_json to trx-frontend Cargo.toml to support this.

Three hot-path optimizations in the client polling loop and SSE
spectrum stream:
- Set TCP_NODELAY on the client→server connection so each framed
JSON command is sent immediately instead of being held up to 40 ms
by Nagle's algorithm.
- Wrap SpectrumData in Arc<> inside SharedSpectrum. snapshot() was
cloning the full bin vector (~8 KB for 2048 f32 bins) for every SSE
/spectrum client on every 40 ms tick. With N clients that is N×8 KB
per tick; now replace() pays one Arc::new() and each client gets an
O(1) pointer clone.
- Eliminate the format!("{}\n", payload) intermediate String in the
three send_command / send_command_no_state_update / send_get_rigs
call sites. Push '\n' in-place on the serialised payload String
instead of allocating a second buffer.

Three causes of >30 s SSE stalls:
1. SPECTRUM_IO_TIMEOUT was 300 ms — transient server jitter triggered
false-positive spectrum failures and immediate TCP disconnects.
Raised to 1 s to tolerate brief load spikes.
2. reconnect_delay was never reset after a successful TCP connect, so
after a few spectrum-induced disconnects the backoff reached 10 s.
Each new disconnect then cost 10 s of stale SSE state, and several
cycles accumulated to >30 s. Reset to 1 s on every successful
TCP connect so recovery stays fast.
3. SSE pings were emitted as comments (": ping"), which EventSource
never exposes to onmessage. lastEventAt was therefore never updated
by pings, causing the JS heartbeat to force-reconnect every ~20 s
even on healthy, stable connections. Changed to a named "ping"
event and added es.addEventListener("ping", …) to update lastEventAt.

Replace the JSON f32 array (~7.5 KB/frame) with a named SSE event "b"
carrying base64-encoded i8 bins (~1.4 KB/frame, ~5x reduction):
event: b
data: {center_hz},{sample_rate},{base64_i8_bins}
1 dB per step covers the -128…+127 dBFS display range, sufficient for
visualization. RDS is stripped from the spectrum frame and emitted as a
separate named "event: rds" only when the payload changes. The JS
decoder uses atob() + sign-extension to reconstruct the float bin array.
A minimal inline base64 encoder is added server-side (no new crate).

is kept at 1 MB for normal messages; a separate 16 MB limit is applied
only to the compressed history type.

Two bugs triggered by a SoapySDR IQ overflow:
1. Spectrum dies permanently (trx-client): when GetSpectrum times out
(300ms SPECTRUM_IO_TIMEOUT), the error was silently swallowed and
the spectrum buffer cleared. The in-flight response remained in the
TCP receive buffer, desynchronising all subsequent reads so every
poll kept failing. Fix: propagate the error so handle_connection
returns and the outer loop reconnects, restoring TCP sync.
2. CTRL+C hangs trx-server: after IQ overflow, the sdr-iq-read thread
can get stuck in a blocking SoapySDR/USB call (deactivate/activate
with no timeout). Tokio received SIGINT and aborted async tasks, but
the process could not exit while the native thread was blocked in
uninterruptible I/O. Fix: call std::process::exit(0) after the
graceful shutdown sequence so the OS forcibly terminates all threads.
