- Add rebuildHeatmap(paramMeta): resets rawParamValues/_lastSentParams and rebuilds #heatmap-cells from engine paramMeta; colors from SYNTH_PARAM_COLORS for C15, _colorFromGroup() hash for other engines - Replace static SYNTH_PARAM_NAMES/COLORS lookups in buildHeatmap, setHeatmapValue, and showParamPopup with activeEngine.paramMeta[index] lookups - Scope MIDI CC localStorage key per engine via midiCCStorageKey() - Add reloadMidiCCMap() helper; called in setActiveEngine() after engine switch - loadCCMap/saveCCMap in midi-cc-map.js accept optional key parameter
