- Replace blocking stdout.read() with select()-based non-blocking reads
so the decode thread responds to stop within 0.5s
- Make stop() non-blocking by releasing the lock before terminating the
process and removing the redundant wait()
- Move initial scanning SSE event from start() into the decode thread so
it fires after the frontend EventSource connects
- Update frontend stop() to give immediate UI feedback before the fetch

rtl_fm subprocess failures (missing tool, no SDR hardware) were silent —
add tool-path check and post-spawn health check in _start_pipeline(),
show errors prominently in the strip status bar (red text + red dot),
and include error detail in scheduler skip events.

Flash the Start button itself with amber pulse when clicked without a
station selected, and show "Select Station" in the strip status text
right next to the button so the error is immediately visible.
Add a 24-hour timeline bar with broadcast window markers, red UTC time
cursor, and countdown boxes (HRS/MIN/SEC) that tick down to the next
broadcast. Broadcasts show as amber blocks on the timeline track with
imminent/active visual states matching the weather satellite pattern.

Fix silent failure when starting without station/frequency selected by
flashing amber on status text and dropdowns. Add auto-capture scheduler
that uses fixed UTC broadcast schedules from station data to
automatically start/stop WeFax decoding at broadcast times.

Implement HF radiofax decoding with custom Python DSP pipeline
(rtl_fm USB → Goertzel/Hilbert demodulation), 33-station database
with broadcast schedules, audio waveform scope, live image preview,
and decoded image gallery. Amber/gold UI theme for HF distinction.

1. Stop Monitor button was disabled during shared monitor retunes
because _syncMonitorButtons disabled the button whenever
_startingMonitor was true, even if the monitor was already active.
Now only disables during initial start (not retunes).
2. Click-to-tune was inconsistent because the shared monitor retune
(rearm after capture restart) captured the center frequency early
in _startMonitorInternal, then sent it via POST to /audio/start.
If the user clicked a new frequency during the async reconnect,
the POST carried the stale frequency and could override the click.
Now retunes use the live _monitorFreqMhz and send a WS tune sync
after reconnecting to ensure the backend has the latest VFO.
When restarting capture for a new frequency, the USB handle from the
just-killed process may not be released by the kernel in time for the
rtl_test probe inside claim_sdr_device. Add retry logic (up to 4
attempts with 0.4s backoff) matching the pattern already used by the
audio start endpoint.
Also clean up stale shared-monitor state in the frontend error handler
so the monitor button is not left disabled when the capture restart
fails.
When changing frequency with shared monitor active, the monitor retune
could be silently dropped if a previous retune was still in-flight,
leaving the UI stuck on "Starting <freq>". After stopping and restarting
the waterfall, the monitor button could remain disabled because
_startingMonitor was never reset and _monitorRetuneTimer was not cleared.
- Cancel in-flight monitor start when queuing a new retune
- Always clear _pendingSharedMonitorRearm in started handler
- Clear _monitorRetuneTimer and reset _startingMonitor in stop()
stop() sets _ws = null before the async onclose fires, so the handler
now early-returns when _ws is null instead of showing the misleading
"WebSocket closed before ready" retry message.

- _waitForPlayback now only succeeds on playing/timeupdate events, not
loadeddata/canplay which fire from just the WAV header before real
audio arrives
- stopMonitor() pauses audio and updates UI immediately instead of
blocking on the backend stop request (1+ second delay)
- Reduced backend audio stop sleep from 1.0s to 0.15s; the start
retry loop already handles USB contention

- Waterfall: load waterfall.css eagerly in <head> instead of lazily on
mode switch; the lazy inject raced with the panel becoming visible,
leaving unstyled HTML for up to 20 s on cold cache
- WebSDR: await a requestAnimationFrame before calling Globe()(mapEl) so
the browser has committed the display:flex layout and clientWidth/
clientHeight are non-zero; previously the globe WebGL renderer was
created at 0×0 (especially on warm-cache refreshes) and could not
recover via the deferred resize calls
- Bump version to 2.22.2

- Add missing setThemePreference() and setAnimationsEnabled() functions
to settings-manager.js; sync theme/animations dropdowns in _updateUI
- Fix base.html toggleTheme() saving to wrong localStorage key ('theme'
instead of 'intercept-theme'), causing theme not to persist in ADS-B
and AIS dashboards; also sync button icon and persist to server
- Add [data-theme="light"] CSS variable overrides to adsb_dashboard.css
and ais_dashboard.css so the dashboards respond to light theme
- Fix GPS sky view canvas (gps.js) to read grid/label colours from CSS
variables instead of hardcoded dark hex values; add MutationObserver
to redraw immediately on theme change
- Fix satellite_dashboard.html polar plot functions to read background,
accent and text colours from CSS variables
Closes#139
