Fix app becoming unresponsive when two browser windows are open: the
root cause was HTTP/1.1 connection pool exhaustion (6-connection limit
per origin). VoiceAlerts was opening 3 SSE streams per window by
default, so two windows produced 8 connections and permanently starved
all regular HTTP requests.
- voice-alerts.js: default all streams to false (opt-in) to stay within
the browser connection limit; existing user preferences in localStorage
are preserved
- routes/alerts.py: replace direct AlertManager.stream_events() with
sse_stream_fanout so both windows receive every alert instead of
competing for the same queue
- routes/bluetooth_v2.py: same fanout fix via subscribe_fanout_queue,
preserving named SSE events (device_update, scan_started, etc.)
Also includes accumulated UI/theming changes: accent-cyan CSS variable
sweep across mode CSS/JS files, standalone dashboard pages, template
updates, satellite TLE data refresh, and tile provider default rename.

Each dashboard is a separate HTML page that doesn't inherit the main SPA's
localStorage restore. Add a synchronous tier-restore script before CSS loads
so html[data-ui-tier] selectors fire on first paint.
Also add enhanced/lean tier override blocks to each dashboard CSS to remap
the dashboard-local variables (--bg-dark, --bg-panel, --radar-cyan, etc.)
that variables.css doesn't cover, and add lean-mode scanline/bg hide rules
since components.css is not loaded on these pages.

- Remove 'METEOR-M2' (NORAD 40069) from WEATHER_SAT_KEYS — it has no
entry in WEATHER_SATELLITES and no dropdown option, so the Capture
button was silently scheduling against the wrong satellite
- Dispatch a 'change' event after setting satSelect.value in preSelect()
and startPass() so any UI listeners (frequency display, mode info)
update correctly when the satellite is set programmatically

Fills the empty space below the sky view circle with a compact
three-column AOS / TCA / LOS readout (time + azimuth/elevation)
and a duration + max elevation footer line.
Populated by drawPolarPlot() when a pass is selected; shows a
placeholder prompt otherwise.

Setting both width:100% and height:100% made CSS ignore aspect-ratio,
stretching the drawing buffer non-uniformly into the tall container.
Fixed by keeping only width:100% + max-height:100% so aspect-ratio:1/1
clamps the height and the element stays square.
Draw functions now use canvas.offsetWidth for the square buffer size.

- Remove align-self: start from .polar-container so the grid row's
minmax(260px, 340px) height is actually respected
- Switch #polarPlot to aspect-ratio: 1/1 so the canvas is always square
- Fix both draw functions to size canvas from getBoundingClientRect on
the canvas itself (not parent) using min(width, height) for a square plot
- Remove min-height from .dashboard to prevent empty space below content
on narrow/mobile screens where stacked panels are shorter than 720px

- Move _passAbortController = null to after response.json() so the retry
scheduler cannot see a false idle state mid-parse, increment
_passRequestId, and discard the in-flight response — this was causing
non-ISS satellites to show no passes intermittently
- Add _computeSlantRange() helper using 3D ECEF geometry
- Update applyTelemetryPosition to compute slant range from SSE lat/lon/
altitude, giving distance updates at 1Hz instead of 5s HTTP poll rate

updateCountdown fell back to passes[0] even when it was in the past,
showing 00:00:00:00 with a stale satellite name indefinitely. Now
displays a clear 'NO UPCOMING PASSES' state with '--' for all fields
when no future pass exists in the current prediction window.
Consolidated to a single active-request guard with cleanup in finally.
The previous pattern had redundant null-checks across try and catch, and
an always-false check on a controller that was already null. Cancel-on-
new-request is now explicit before creating the new controller.
METEOR-M2 (NORAD 40069) is a weather satellite with LRPT downlink but
was missing from WEATHER_SAT_KEYS, so no capture button appeared in
the pass list. Adds it alongside M2-3 and M2-4.
Previously currentPos only had lat/lon, so the updateTelemetry fallback
(used before first live position arrives) always showed '---' for
altitude/elevation/azimuth/distance. currentPos now includes all fields
computed from the request observer location. updateTelemetry simplified
to delegate to applyTelemetryPosition.
Adds a 'source' param to handleLivePositions. The SSE path ('sse') only
applies lat/lon/altitude/groundTrack since the server-side tracker has
no per-client location. The HTTP poll path ('poll') owns all observer-
relative data and the visible-count badge.
- OBSERVATION PROFILES section with list of configured satellites
- + ADD button opens inline form pre-filled from currently selected satellite
and SatNOGS transmitter data (frequency, decoder type auto-detected)
- EDIT / ✕ buttons per profile row
- Form fields: frequency, decoder (FM/AFSK/GMSK/BPSK/IQ-only), min elevation,
gain, record IQ checkbox
- UPCOMING PASSES section below profiles with friendlier empty-state message
- gsOnSatelliteChange hook updates form when satellite dropdown changes
- CSS for .gs-form-row, .gs-profile-item, .gs-form-label
