Hit area: was Math.max(dotSize * 2, 15) — up to 24px radius around a 4px
dot. Now the CSS hover-flicker is fixed the large hit area is unnecessary
and was the reason dots activated when merely nearby. Changed to dotSize + 4
(proportional, 4px padding around the visual circle).
Overlap spread: compute all band positions first, then run an iterative
push-apart pass (spreadOverlappingDots) that nudges any two dots whose
arc gap is smaller than 2 * maxHitArea + 2px apart. Positions within a
band are stable across renders (same hash angle, same band = same output
before spreading) so dots don't shuffle on every update.
Z-order: sort visible devices by rssi_current ascending before rendering
so the strongest signal lands last in SVG order and receives clicks when
dots stack.

Replace continuous estimated_distance_m-based radius with proximity band
snapping (immediate/near/far/unknown → fixed radius ratios of 0.15/0.40/
0.70/0.90). The proximity_band is computed server-side from rssi_ema which
is already smoothed, so it changes infrequently — dots now only move when
a device genuinely crosses a band boundary rather than on every RSSI
fluctuation.
Also removes the client-side EMA and positionCache added in the previous
commit, and reverts CSS style.transform back to SVG transform attribute to
avoid coordinate-system mismatch when the SVG is displayed at a scaled size.

The remaining jitter after the in-place DOM rewrite was caused by RSSI
fluctuations propagating directly into dot positions on every 200ms
update cycle.
Two fixes:
1. Client-side EMA (alpha=0.25) on x/y coordinates per device. Each
render blends 25% toward the new raw position and retains 75% of the
smoothed position, filtering high-frequency RSSI noise without hiding
genuine distance changes. positionCache is keyed by device_key and
cleared on device removal or radar reset.
2. CSS transition (transform 0.6s ease-out) on each wrapper element.
Switching from SVG transform attribute to style.transform enables
native CSS transitions, so any remaining position change (e.g. a band
crossing) animates smoothly rather than snapping.

Instead of rebuilding devicesGroup.innerHTML on every render, mutate
existing SVG elements in-place (update transforms, attributes, class
names) and only create/remove elements when devices genuinely appear
or disappear from the visible set.
This eliminates the root cause of both the jitter and the blank-radar
regression: hover state can never be disrupted by a render because the
DOM elements under the cursor are never destroyed. The isHovered /
renderPending / interactionLockUntil state machine and its associated
mouseover/mouseout listeners are removed entirely — they are no longer
needed. A shared buildSelectRing() helper deduplicates the animated
selection ring construction used by renderDevices() and
applySelectionToElement(). Closes#143.

Replace capture-phase mouseenter/mouseleave with bubbling mouseover/mouseout
for tracking hover state in the ProximityRadar component.
The capture-phase approach caused two problems:
1. Moving between sibling child elements (hit-area → dot circle) fired
mouseleave, prematurely clearing isHovered and triggering a DOM rebuild
that caused visible jitter.
2. When renderDevices() rebuilt innerHTML, the browser fired mouseleave for
the destroyed element with relatedTarget pointing at the newly created
element at the same position, leaving isHovered permanently stuck at true
and suppressing all future renders.
The fix uses mouseover/mouseout (which bubble) with devicesGroup.contains()
to reliably detect whether the cursor genuinely left the device group, immune
to innerHTML rebuilds. Fixes both WiFi and Bluetooth proximity radars as they
share this component. Closes#143.

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

gpsd sends multiple SKY messages per cycle — some contain only DOP
values with an empty satellites array. Previously this would overwrite
the satellite list, causing the sky view to flicker empty. Now DOP-only
SKY messages preserve the existing satellite list. Also adds a 5-second
polling fallback for satellite data since SSE can miss sky updates due
to queue contention.

Digital voice is intermittent — dsd-fme only outputs PCM during active
voice transmissions. Without input, ffmpeg never wrote the WAV header
and the browser got an empty response. Add an audio bridge thread that
feeds 100ms silence chunks during voice gaps so ffmpeg always has input
and the browser receives a continuous WAV stream. Add auto-reconnect
on the frontend if the audio stream drops while the decoder is running.

Stream decoded digital voice audio to the browser via ffmpeg pipeline
(dsd-fme 8kHz PCM → ffmpeg → 44.1kHz WAV → chunked HTTP). Persist
frequency/protocol/gain/ppm settings in localStorage so they survive
page navigation. Add bookmark system for saving and recalling frequencies.
