/**
 * RiffDex's entry into alphaTab (https://github.com/CoderLine/alphaTab, MPL-2.0): its Guitar Pro (3–8) and MusicXML
 * importers and the score model they produce, without alphaTab's rendering, audio or browser set-up.
 * scripts/alphatab/build-importer.mjs bundles this with alphaTab's unchanged source into
 * src/vendor/alphatab/alphatab-importer.js; src/vendor/alphatab/README.md says how and why.
 *
 * The importers are tried in the order alphaTab's own ScoreLoader.loadScoreFromBytes tries them (Environment.buildImporters),
 * leaving out the ones RiffDex doesn't offer: Capella and alphaTex.
