Dashboard
- Selectable main sensor (gauge) + sub sensor, 10 selectable values
(landscape 5 left + 5 right, portrait 2x5 on one screen) and 4
selectable flags; long-press to change; persisted.
- Flags: the requirement examples (MIL, FAN Out, VTEC Out, Knock, WBO /
IAT / CLT Error - errors derived from the stored DTC bits) plus the
other S300 status bits (cuts, launch, closed loop, VTP, AC, brake).
- Record button moved to the app bar; debug screen moved to Settings.
Sensor list: 1 column on phone portrait, 2 on tablet/landscape; name,
unit, min/max, segmented bar and value.
Graph: auto-scaled Y, window max/min, current value, seconds axis and a
touch cursor; RPM/MAP/TPS/ECT by default.
Units: km/h|mph, degC|degF, kPa|bar|psi (display only), persisted.
Light/dark: palette is a ThemeExtension used by every screen; theme
persisted. SafeArea keeps content off the side navigation bar.
Datalog playback now drives the dashboard, list, graph and DTC screen,
with the playback bar on the main screen and seek updating the displays.

- Rewrite S300 and KPro DTC tables from hvbt_protocol.pdf (the previous
tables did not match the PDF; e.g. ERR01.6 is P0350 IGM, not P1361).
- Clear DTC: the adapter never echoes the documented ack, but the ECU does
clear (bench: 3 of 4 codes cleared, P0350 re-set at once as an active
fault). Judge success from the live ERR bytes; wait only 0.6 s for the
ack so polling resumes, and report "N of M cleared".
- Set the ECU protocol from the adapter name (S300/KPro) on connect; a
stale KPro setting made an S300 adapter look unresponsive.

Work that was previously only in the local working tree:
- Rename fuelCut -> fuelPump (SW2 bit2, active-low, live-confirmed)
- ECT/IAT/BAT moved to live-confirmed offsets 33/34/36
- S300 template-frame detection with hold-last-good logic
- Persist ECU type in SharedPreferences; drop per-connect protocol dialog
- Official-protocol probe and DTC clear on the debug/DTC screens
- Sanity clamp for multi-byte fields; scrollable vertical dashboard
- docs/HANDOFF.md
Includes temporary [DBG]/[KDBG] prints, removed in the next commit.

- Implemented RawFrameDebugScreen for displaying ECU frame data and diagnostics.
- Created DtcScreen to show active Diagnostic Trouble Codes (DTCs) with detailed descriptions.
- Added DtcRow widget for individual DTC representation.
- Introduced GraphScreen for visualizing sensor data over time with customizable time windows.
- Developed SensorListScreen to display available sensors and their current values.
- Enhanced SettingsScreen with options for Bluetooth connection, ECU protocol selection, polling interval, and theme settings.
- Added AppColors and AppTheme for consistent theming across the application.
- Implemented BtStatusChip to show Bluetooth connection status in the app bar.
- Created RecordFab for starting and stopping data recording sessions.
