Add 8 enhancements to the spectrum display:
1. Noise floor reference line — dashed horizontal line at estimated
noise floor (15th-percentile heuristic)
2. Peak frequency labels — top 5 strongest peaks labeled with
frequency text on the spectrum canvas
3. Crosshair lines — vertical + horizontal guide lines follow
cursor on hover for precise frequency/dB reading
4. Zoom indicator + minimap — shows current zoom level (e.g. "4.0x")
and a minimap showing the visible window within the full span
5. dB range control — new Range input alongside Floor, with Auto
button updating both; allows direct control of vertical span
6. Keyboard shortcuts — Arrow Left/Right to pan, +/- to zoom,
0 to reset zoom; documented in hint bar
7. Full waterfall panel — WebGL waterfall canvas below the spectrum
plot, synchronized with zoom/pan, with scroll/click/drag support
8. Signal overlay extended — overlay height now includes waterfall
canvas for consistent BW/bookmark/freq marker coverage

Nudge state watch when server_connected goes false so SSE delivers the change. Frontend applies a desaturated frost + banner instead of a blocking overlay, keeping the last-known state visible.

The map module was tagging all decode markers (APRS, AIS, VDES,
FT8/FT4/FT2/WSPR locators) with the global rig picker's active rig
instead of the actual source rig. This made the map's own rig filter
dropdown ineffective in multi-rig setups.
- Add rig_id field to all decode message structs (AisMessage,
VdesMessage, AprsPacket, CwEvent, Ft8Message, WsprMessage)
- Set rig_id on messages in audio_client before broadcasting, using
the actual rig connection identifier
- Update history collector to prefer message rig_id over the global
active rig fallback
- Pass rig_id through plugin normalize functions (AIS, APRS, VDES,
HF-APRS) so it reaches the map add functions
- Update all map marker functions (aprsMapAddStation, aisMapAddVessel,
vdesMapAddPoint, mapAddLocator) to use the message's rig_id with
fallback to the global picker for backward compatibility

Decoder bar overlays (AIS, VDES, FT8, APRS, RDS) use backdrop-filter
blur for a frosted-glass look in the browser, but this can't be
replicated on canvas — resulting in opaque blocks covering the spectrum
in screenshots. Cap their background alpha to 0.35 when rendering to
the snapshot canvas.

Radio paths now originate from the rig that decoded the message rather
than the currently selected rig. Bookmark locators no longer draw radio
paths. Rig switch no longer tears down decode pipeline since it is

The bookmark color palette is derived from CSS variables (--accent-yellow,

The HTTP round-trip for set_freq blocks on the server processing the
command (mpsc → TCP → rig hardware → response). With optimistic local
updates, CSS overlay, and SSE snap-back guard already in place, there is

click, RDS AF tune) now return immediately after the optimistic update.

When the user changes frequency, applyLocalTunedFrequency sets lastFreqHz
optimistically. But the SSE state stream could push back the old server
frequency before set_freq completes, causing the marker to snap back then
forward. Add a sequence-guarded _freqOptimisticHz that suppresses stale
SSE frequency updates while a set_freq is in flight.

Each browser tab can now subscribe to a specific rig's spectrum and
audio independently via ?rig_id= query params on /spectrum and /audio.
The remote client polls spectrum for all rigs with active subscribers
and routes responses to per-rig watch channels. Virtual channel
commands are routed through per-rig senders with global fallback.

select_rig no longer mutates remote_active_rig_id — only the per-session
mapping is updated. This eliminates cross-tab leaking entirely: each tab
carries its own rig_id via the session manager, /events?rig_id, and
/status?rig_id query params.
The global remote_active_rig_id now only serves as the startup default
for brand-new sessions that have no rig_id yet.
Also fix the About section to show the per-tab lastActiveRigId instead
of the server's global active_rig_id.

pollFreshSnapshot() fetches GET /status on every SSE connect/reconnect,
but /status always returned the global selected rig's state, overwriting
the per-tab display with whichever rig was last switched to globally.
Now pollFreshSnapshot passes rig_id as a query param and the /status
endpoint uses the per-rig watch channel when provided, matching the
/events behavior for true per-tab rig isolation.

After select_rig stopped mutating the global remote_active_rig_id for
session-aware clients, SSE reconnects would fall back to the old global
default instead of the newly selected rig. Now connect() passes
lastActiveRigId as a rig_id query param to /events, and the server
prefers it over the global default when present.
