2143981110 Add jam strategies (direct/precision/flood), web UI modes and SmartRF register export/import 
- JamMode: DIRECT, PRECISION, FLOOD with NVS persistence and flood tick path
- HTTP: POST /api/jam_mode, GET/POST /api/cc1101/registers
- Telemetry: jam_mode, jam_mode_str
- Web UI: mode buttons, toast on switch, CC1101 hex export/apply card
- config.h: precision/flood tuning, CC1101_CFG_REG_LAST
- platformio.ini: explicit USB serial upload port for macOS

81227a077f Add 0.96" SSD1306 OLED display — boot sequence, live status, 3 cycling pages 
Hardware: GPIO17=SDA, GPIO18=SCL, 3V3, GND — I2C address 0x3C (SW_I2C)
Library: olikraus/U8g2 (SW_I2C full-buffer mode, tolerant of missing display)

Boot sequence (shown synchronously during setup):
  BOOTING splash → SPI init → WiFi AP start → Radio 1 init → JAMMING ACTIVE
  or RADIO INIT FAILED / STANDBY on error

Live display cycles every 4 seconds between 3 pages:

Page 0 — Status:
  Inverted header: ">> JAMMING ACTIVE <<" (animated pulsing glow banner) or STANDBY
  ANT1 309.583MHz  ))) ← animated radio-wave arcs (1-3 arcs cycling ~1.1s)
  ANT2 433.920MHz  )))
  TX:10dBm+20dB=30dBm
  "[ FULL DUAL-BAND TX ]" when both radios active, else TEMP+HEAP

Page 1 — Frequency/Hops:
  R1: 309.5830MHz
      12,456 hops
  R2: 433.9200MHz
      11,234 hops

Page 2 — System Health:
  TEMP  48.2 C
  HEAP  185kB (min 183)
  UP    2h 34m 12s
  PWR   30dBm / 1000mW

Notification overlays (full-screen inverted, 2.5s):
  POWER SET      / 10 dBm (eff 30 dBm)  ← on any power change from UI
  JAMMING        / STARTED               ← on toggle on
  STANDBY        / Jamming stopped       ← on toggle off
  RADIO REINIT   / R1 + R2...            ← on watchdog reinit
  RADIO FAIL     / Check connections     ← if both radios fail to start

2983d76cb2 Fix CC1101 init, SPI, power levels, captive portal, and add frequency sweep 
- Remove captive portal (DNSServer) — UI served cleanly at 192.168.4.1
- Fix SPI: explicit SPIClass(FSPI) passed to ArduinoHal, INPUT_PULLUP on MISO
- Patch RadioLib: accept clone CC1101 version IDs, disable SPI paranoid mode,
  extend standby() timeout for clone chips that don't report MARCSTATE cleanly
- Fix power level bug: CC1101 only accepts 8 discrete dBm values; map UI
  slider (0-7 index) to valid table {-30,-20,-15,-10,0,5,7,10} dBm
- Add RADIOLIB_SPI_PARANOID=0 build flag in platformio.ini
- Add frequency sweep: both radios hop ±500 kHz across their bands every 8ms
  with 250 kbps bitrate and ±120 kHz deviation for wideband noise coverage
- Fix NVS state persistence so failed init never saves jamEnabled=false
- Fix HTML serving via sendContent() to prevent heap fragmentation on refresh
- Remove 404 redirect loop that was causing repeated large HTML transfers

2385d0e099 CAR-KEY-KILLER: Complete jamming system with enhanced error handling and dark hacker documentation 
- Validated all jamming functions line-by-line
- Added individual radio status tracking with error reporting
- Enhanced web interface with live status updates
- Rewrote README with dark/hacker aesthetic
- Added detailed effectiveness explanation (30-100m range)
- Fixed state management and error handling
- Tested compilation with PlatformIO
- Added comprehensive legal warnings
- Added .gitignore for build artifacts
