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.
