Strong passes at 40 dB (the previous default) cause RTL-SDR ADC clipping,
producing a distorted IQ stream that SatDump cannot lock onto. 30 dB is
a safer starting point that still captures weak passes cleanly.
Also adds a UI hint below the gain control explaining the saturation issue.
Closes#185
- Fix SSE fanout thread AttributeError when source queue is None during
interpreter shutdown by snapshotting to local variable with null guard

The CSS ::after dot positioning was unreliable across fonts and sizes.
Switch to an inline SVG of the "i" glyph (green dot + cyan stem/bars)
extracted from the logo — renders pixel-perfect at any size.

The dotless i (ı) wasn't rendering in all fonts. Switch to a regular "i"
with the green dot CSS overlay positioned on top of the native dot.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Matches the logo icon — the "i" in iNTERCEPT now renders with a cyan
letter and green dot via CSS, consistent across the main header, welcome
card, dashboard headers, help modal, settings modal, and all popout pages.

ensureModeScript() used document.body.appendChild() to load lazy mode
scripts, but the preload for ?mode= query params runs in <head> before
<body> exists, causing all deep-linked modes to silently fail.
Also fix cross-mode handoffs (BT→BT Locate, WiFi→WiFi Locate,
Spy Stations→Waterfall) that assumed target module was already loaded.

Add WiFi Locate mode for locating access points by BSSID with real-time
signal meter, distance estimation, RSSI history chart, and audio

presets (Free Space/Outdoor/Indoor), and signal-lost detection.
Also includes:
- Mobile navigation reorganized into labeled groups (SIG/TRK/SPC/WIFI/INTEL/SYS)
- flask-limiter made optional with graceful degradation
- Fix radiosonde setup missing semver Python dependency
- Documentation updates (FEATURES, USAGE, UI_GUIDE, GitHub Pages site)

- Fix XSS: escape ASCII output in innerHTML via escapeHtml()
- Fix deadlock: use put_nowait() for queue ops under ook_lock
- Fix SSE leak: add ook to moduleDestroyMap so switching modes
closes the EventSource
- Fix RSSI: explicit null check preserves valid zero values in
JSON export
- Add frame cap: trim oldest frames at 5000 to prevent unbounded
memory growth on busy bands
- Validate timing params: wrap int() casts in try/except, return
400 instead of 500 on invalid input
- Fix PWM hint: correct to short=0/long=1 matching rtl_433
OOK_PWM convention (UI, JS hints, and cheat sheet)
- Fix inversion docstring: clarify fallback only applies when
primary hex parse fails, not for valid decoded frames

Replace hardcoded frequency buttons with localStorage-backed presets.
Default presets are standard ISM frequencies (433.920, 315, 868, 915 MHz).
Users can add custom frequencies, right-click to remove, and reset to
defaults — matching the pager module pattern.

- Fix double-scroll by switching ookOutputPanel to flex layout
- Keep decoded frames visible after stopping (persist for review)
- Wire global Clear/CSV/JSON status bar buttons to OOK functions
- Hide default output pane in OOK mode (uses own panel)
- Add command display showing the active rtl_433 command
- Add JSON export and auto-scroll support
- Fix 0x prefix stripping in OOK hex decoder
- Fix PWM encoding hint text

- Timing presets: five quick-fill buttons (300/600, 300/900, 400/800, 500/1500, 500 MC)
that populate all six pulse-timing fields at once — maps to CTF flag timing profiles
- RSSI per frame: add -M level to rtl_433 command; parse snr/rssi/level from JSON;
display dB SNR inline with each frame; include rssi_db column in CSV export
- Auto bit-order suggest: "Suggest" button counts printable chars across all stored
frames for MSB vs LSB, selects the winner, shows count — no decoder restart needed
- Pattern filter: live hex/ASCII filter input above the frame log; hides non-matching
frames and highlights matches in green; respects current bit order
- TSCM integration: "Decode (OOK)" button in RF signal device details panel switches
to OOK mode and pre-fills frequency — frontend-only, no backend changes needed

The "Mute" button on pager cards persists muted addresses to
localStorage with no visible indicator, making it easy to
accidentally hide an address and forget about it. This caused
flag fragment messages on RIC 1337 to silently disappear.
- Add "X muted source(s) — Unmute All" indicator to sidebar
- Stop persisting hideToneOnly filter across sessions so the
default (show all) always applies on page load
- Remove default checked state from Tone Only filter checkbox

Add theme-aware severity/neon CSS variables and replace hardcoded hex

Full-stack meteor scatter monitoring mode that captures IQ data from
an RTL-SDR, computes FFT waterfall frames via WebSocket, and runs a
real-time detection engine to identify transient VHF reflections from
meteor ionization trails (e.g. GRAVES radar at 143.050 MHz).
Backend: MeteorDetector with EMA noise floor, SNR threshold state
machine (IDLE/DETECTING/ACTIVE/COOLDOWN), hysteresis, and CSV/JSON
export. WebSocket at /ws/meteor for binary waterfall frames, SSE at
/meteor/stream for detection events and stats.
Frontend: spectrum + waterfall + timeline canvases, event table with
SNR/duration/confidence, stats strip, turbo colour LUT. Uses shared
SDR device selection panel with conflict tracking.

Move tracking state, balloon count, last update, and waveform from the
sidebar into a stats strip above the map, matching the APRS strip pattern.

Reusable SVG bar waveform (SignalWaveform.Live) that animates in response
to incoming SSE data — idle breathing when stopped, active oscillation
proportional to telemetry update frequency, smooth decay on signal loss.
Integrated into radiosonde Status section with ping() on each balloon
message and stop() on tracking stop. Also hardens the fetch error path
to show a readable message instead of a JSON parse error when the server
returns HTML.

SSE EventSource connections for AIS, ACARS, VDL2, and radiosonde were
not closed when switching modes, causing fd exhaustion after repeated
switches. Also fixes socket leaks on exception paths in AIS/ADS-B
stream parsers, closes subprocess pipes in safe_terminate/cleanup, and
caches skyfield timescale at module level to avoid per-request fd churn.

Re-implements envelope detection on top of the rewritten Morse decoder.
Addresses PR #160 review feedback:
- Rebase: rebuilt on current upstream/main (lifecycle state machine)
- Gap thresholds: 2.0/5.0 for envelope only; goertzel keeps 2.6/6.0
- Frequency validation: max_mhz=1766 for envelope, 30 for goertzel
- Tests: EnvelopeDetector unit tests + envelope-mode decoder test
- Envelope uses direct magnitude threshold (no SNR/noise ref)
- Goertzel path completely unchanged

The stop button appeared unresponsive because UI updates waited for the
server response. If the fetch hung or errored, the user saw nothing.
Now the UI updates immediately (matching the pager stop pattern) and
the server request happens in the background.

Enable direct sampling (-D 2) for RTL-SDR at HF frequencies below 24 MHz
so rtl_fm can actually receive CW signals. Add startup health check to
detect immediate rtl_fm failures. Push stopped status event from decoder

Fix "What's New" section shifting up/down on smaller screens (#157) by
