+/**
+ * Plugin categories are derived from the official Steinberg VST3 Plug-in
+ * Type definitions (plugType) provided by the VST3 SDK.
+ *
+ * The VST3 SDK defines a large set of hierarchical category strings
+ * (e.g. "Fx|Dynamics", "Fx|EQ", "Instrument|Synth") which serve multiple
+ * purposes including host routing, UI grouping, and capability flags.
+ *
+ * This project intentionally normalizes and consolidates those categories
+ * into a smaller, format-agnostic set suitable for a plugin registry and
+ * tagging system. Not all VST3 plugType values map 1:1 to public categories.
+ *
+ * Authoritative source (VST3 SDK):
+ * https://steinbergmedia.github.io/vst3_doc/vstinterfaces/group__plugType.html
