6ea34a4c60 fix(weather-sat): lower default gain to 30 dB to prevent ADC saturation
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

90281b1535 fix(modes): deep-linked mode scripts fail when body not yet parsed
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.

e687862043 feat: UI/UX overhaul — CSS cleanup, accessibility, error handling, inline style extraction
Phase 0 — CSS-only fixes:
- Fix --font-mono to use real monospace stack (JetBrains Mono, Fira Code, etc.)
- Replace hardcoded hex colors with CSS variables across 16+ files
- Merge global-nav.css (507 lines) into layout.css, delete original
- Reduce !important in responsive.css from 71 to 8 via .app-shell specificity
- Standardize breakpoints to 480/768/1024/1280px

Phase 1 — Loading states & SSE connection feedback:
- Add centralized SSEManager (sse-manager.js) with exponential backoff
- Add SSE status indicator dot in nav bar
- Add withLoadingButton() + .btn-loading CSS spinner
- Add mode section crossfade transitions

Phase 2 — Accessibility:
- Add aria-labels to icon-only buttons across mode partials
- Add for/id associations to 42 form labels in 5 mode partials
- Add aria-live on toast stack, enableListKeyNav() utility

Phase 3 — Destructive action guards & list overflow:
- Add confirmAction() styled modal, replace all 25 native confirm() calls
- Add toast cap at 5 simultaneous toasts
- Add list overflow indicator CSS

Phase 4 — Inline style extraction:
- Refactor switchMode() in app.js and index.html to use classList.toggle()
- Add CSS toggle rules for all switchMode-controlled elements
- Remove inline style="display:none" from 7+ HTML elements
- Add utility classes (.hidden, .d-flex, .d-grid, etc.)

Phase 5 — Mobile UX polish:
- pre/code overflow handling already in place
- Touch target sizing via --touch-min variable

Phase 6 — Error handling consistency:
- Add reportActionableError() to user-facing catch blocks in 5 mode JS files
- 28 error toast additions alongside existing console.error calls

- 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

cde24642ac feat(ook): add persistent frequency presets with add/remove/reset

Default presets are standard ISM frequencies (433.920, 315, 868, 915 MHz).
Users can add custom frequencies, right-click to remove, and reset to

0c3ccac21c feat(ook): add timing presets, RSSI, bit-order suggest, pattern filter, TSCM link
- 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

4c282bb055 feat: add Generic OOK Signal Decoder module
New 'OOK Decoder' mode for capturing and decoding arbitrary OOK/ASK
signals using rtl_433's flex decoder with fully configurable pulse
timing. Covers PWM, PPM, and Manchester encoding schemes.

Backend (utils/ook.py, routes/ook.py):
- Configurable modulation: OOK_PWM, OOK_PPM, OOK_MC_ZEROBIT
- Full rtl_433 flex spec builder with user-supplied pulse timings
- Bit-inversion fallback for transmitters with swapped short/long mapping
- Optional frame deduplication for repeated transmissions
- SSE streaming via /ook/stream

Frontend (static/js/modes/ook.js, templates/partials/modes/ook.html):
- Live MSB/LSB bit-order toggle — re-renders all stored frames instantly
  without restarting the decoder
- Full-detail frame display: timestamp, bit count, hex, dotted ASCII
- Modulation selector buttons with encoding hint text
- Full timing grid: short, long, gap/reset, tolerance, min bits
- CSV export of captured frames
- Global SDR device panel injection (device, SDR type, rtl_tcp, bias-T)

Integration (app.py, routes/__init__.py, templates/):
- Globals: ook_process, ook_queue, ook_lock
- Registered blueprint, nav entries (desktop + mobile), welcome card
- ookOutputPanel in visuals area with bit-order toolbar

ec62cd9083 fix: prevent silent muting from hiding pager messages
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

7311dd10ab feat: add Meteor Scatter mode for VHF beacon ping detection
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.
