sm-26/Source/PluginEditor.cpp
Armin bdd3b38cee Persist engine state in DAW projects, black monochrome panel, expand preset bank 
- Save/load the engine's full parameter set alongside the preset index so
  knob and menu tweaks survive relaunching a song project
- Make the plugin panel black: top/surround laser border and bottom deck
  (rotary + nav keys) are now #000000
- Extend factory bank to 320 categorized presets and add LCD click-to-open
  preset category browser
