gui/widgets.py:
- MultiAxisPlot -- overlay with one Y axis PER UNIT (psi/V/rpm/C/%), linked
ViewBoxes on X, so mixed-scale signals are readable at true values
(base left axis + up to 4 right axes).
- SinglePlot -- one shared axis for the Normalize (% of range) mode.
- ArcGauge -- 270deg arc gauge with peak tick + numeric readout, own dark bg.
- GaugeGrid -- scrollable grid of gauges.
gui/main.py:
- Graph page is now a multi-axis/single-axis sub-stack; Normalize toggles
between true multi-axis (raw) and single-axis (%). curves map key->color;
plot ops route to the active graph widget.
- Gauge View menu enabled (3rd center page); gauges update on tick with peak.
- Theme applies to both plot widgets; profile switch clears graphs/gauges.
Fix: ArcGauge QPen built via setCapStyle (the QPen(...cap=...) kwarg segfaults
PySide6). Validated headless: driving preset -> 6 unit groups across 5 axes,
gauge view renders, normalize round-trips, profile-switch clears cleanly.
obdcore + diagnostics tests still pass.

The stack is portable by construction: PySide6/pyqtgraph/numpy/pyserial all
ship wheels for all three OSes (incl. Apple Silicon); obdcore has no
OS-specific code; the terminal dashboard's only platform code is guarded
(os.name=='nt' vs termios for POSIX = macOS+Linux).
- ARCHITECTURE.md: Cross-platform section -- portability rules (list_ports
only, pathlib, no shelling out, platformdirs for config), the three per-OS
seams (CH340 driver, PyInstaller per-OS packaging, Gatekeeper/SmartScreen).
- README: Setup now covers Windows (CH341SER), macOS (CH34xVCPDriver), Linux
(in-kernel ch341 + dialout group) instead of Windows-only.
No code changes; obdcore tests still pass.

Big ICP readout focused on the cranking scenario:
- Wide ICP bar with the 500-psi firing threshold marked (|)
- Rolling ASCII trace chart of the ICP build-up (10 rows; renders anywhere,
no unicode) -- clearly shows ICP climbing above/below the 500 firing line
- Peak-hold (the crank's max ICP, the money number) + pass/fail verdict
- FICM main / battery / RPM secondaries with sag (min) tracking
- --dash-log writes a CSV (t,icp,ficm,batt,rpm) while you watch
- On exit prints peak ICP + verdict (reached 500 / suspect oil bleed-off)
Validated end-to-end via a mock crank: ICP ramp past 500, peak capture,
battery-sag capture, trace resolution, CSV logging, clean terminal restore.

In-place updating CLI dashboard for watching data while cranking/running.
Pure-ANSI (no new deps; works on Windows 10+ terminals).
- Color-coded gauges (green/yellow/red) by no-start thresholds
- Live min/max per gauge -> captures PEAK ICP during a crank
- ASCII bars for ICP and FICM main voltage
- Presets: crank (ICP/FICM/batt/RPM, fastest), vitals (default), full
- Dead-PID auto-skip keeps refresh rate up when 09xx FICM PIDs no-respond
- --dash-log PATH writes a CSV while you watch (streaming log preserved)
- q=quit, r=reset min/max; cross-platform non-blocking key input
Validated: render + decoders vs the truck's real scan bytes, and the full
dashboard() loop via a mock ELM (ICP climb across the 500psi firing
threshold, peak capture, battery-sag capture, CSV logging, clean exit).

Read stored/pending/permanent DTCs, decode with 6.0-relevant codes flagged,
guarded mode-04 clear (--clear), key live PIDs + battery voltage, and a
6.0 no-start triage checklist. Tested against a CH340 ELM327 v1.5 adapter.
