A single double-click-to-open HTML viewer (no server, no external refs) with
three tabs: browse/filter the 1811-map catalogue (with a "my bike" filter for
mechanical-odo Keihin Bonneville maps), see TuneECU's full editable surface
(tunable parameters, table axes, toggleable devices with SAI/O2/exhaust flagged
as mod targets, live sensors, actuator tests) extracted from the APK resources,
and a drag-drop .bin/.hex table viewer that renders bytes as a configurable
heatmap grid + hex dump for when a ROM dump lands.
build_viewer.py regenerates the HTML from arrays.xml + maps.json.
