CHANGELOG highlights

Added

• Visualizer: Persist folder states (#184) — saveFolderStates/loadFolderStates in state.js; trackFolder helper avoids private lil-gui internals; cleared on full reset
• Visualizer: Reset icon UX (#184) — confirm prompt + one-shot @keyframes spin-once with animationend cleanup
• Visualizer: Build-plate-centered model positioning (#185) — positionMeshOnBuildPlate() called on load, rotation drag-end, and printer change; getBuildPlateDimensions() with localStorage + preset table fallback; updateBuildVolume() rebuilds axes/grid in-place preserving event listeners

Fixed

• G-code metadata version always "Unknown" (#186) — require('../../package.json') → require('../../../package.json') in coders.coffee; metadata test now asserts actual pkg.version
• Dome zenith skin infill suppressed (#187) — even-odd nesting-parity check in findCoveredRegions (cavity.coffee) skips candidates whose bbox centre has odd containment count (i.e. hole paths); preserves lego-stud detection from #182
