generic green circles. Falls back to a green circle marker when no
symbol info is available.

Add a Map sub-tab under Plugins that displays an interactive
OpenStreetMap via Leaflet.js showing:
- Receiver location (blue marker) from server config lat/lon
- APRS station positions (green markers) updated in real-time
The map lazy-initializes on first tab switch, handles tile rendering
on tab visibility changes, and deduplicates station markers by
callsign. Also includes the fallback snapshot lat/lon fields in the
API layer.

Extract the APRS decoder from app.js into its own aprs.js file and add
a new CW (Morse code) decoder plugin in cw.js. The CW decoder uses a
Goertzel tone detector with configurable WPM, tone frequency, and
signal threshold. The Plugins tab now has three sub-tabs: Overview,
APRS, and CW.

Replace bandpass filter envelope detector with delay-and-multiply
frequency discriminator. Add biquad bandpass pre-filter centered at
1700 Hz to remove out-of-band noise. Replace IIR low-pass with
moving-average LPF over half a bit period, which places a null at
2x mark frequency for clean discriminator artifact removal.

Replace the coherent correlation detector with a non-coherent
bandpass filter + envelope detection approach for significantly
better frequency discrimination between mark (1200Hz) and space
(2200Hz) tones. Uses two cascaded 2nd-order IIR biquad filters
per tone with IIR-smoothed envelope detection.
Replace hard clock reset with PLL-style gradual correction for
smoother bit timing recovery.

Add silence detection that resets the demodulator state when RMS
drops below threshold, so burst-mode APRS packets after squelch
activation start with a clean correlator and clock recovery.
Display CRC-failing frames at reduced opacity with a [CRC] tag to
aid debugging. Enhanced CRC-fail console logging now includes
attempted address decode, bit count, and hex dump.

Assign green to VFO A, yellow to VFO B, and deterministic hues
to additional VFOs. The active VFO color is also applied to the
main frequency display. Rework the header title to show
"trx-rs <version> @ <callsign>'s <rig>" instead of "<rig> status".

Fix three bugs in the Bell 202 AFSK demodulator preventing frame
decoding:
- Separate NRZI state from clock recovery (shared lastBit variable
caused NRZI to always output 1)
- Buffer 1-bits in ones counter instead of pushing to frameBits
immediately, preventing flag/stuff bits from contaminating frame
data and corrupting byte alignment
- Detect flags via ones-count on decoded bits instead of shift
register on raw bits
Also add framed packet log container styling, remove redundant
description text, and add debug counters logging pipeline health
to the browser console.

Replace server-side /frontends endpoint with client-side plugin system.
The Plugins tab now has Overview and APRS sub-tabs. The APRS plugin
decodes packets from RX audio using Bell 202 AFSK demodulation (1200
baud), AX.25 frame decoding with NRZI/HDLC, and CRC-16-CCITT
validation. Decoded packets are displayed in a scrolling log.

Close #tab-main properly so the footer and About tab are not nested

Replace the rolling canvas signal graph with a practical signal
measurement feature. The operator can start/stop measurement to
collect signal samples, then view averaged and peak S-unit results.
Also fix signal display to correctly convert dBm wire format to
S-units using standard S-meter scale (S1=-121dBm, S9=-73dBm,
6dB per S-unit).

Add a 120-second TX safety timeout that auto-releases PTT if no mic
data flows (browser crash, disconnect). Timer resets on each audio
callback. Shows countdown in status when < 10s remaining.
Add beforeunload handler that releases PTT via navigator.sendBeacon
when the browser tab is closed during TX.
Detect WebCodecs support on page load and show "Audio requires

Remove dead playBuffer/playNode variables that were declared but
