About this build v0.2.16

What changed

Wide screens now use a dedicated two-column workspace with source and utility panels in a compact side rail.
Transport and master controls stay compact and sticky above a denser, wider mixer.
The Now Playing card remains visible independently of the collapsible source controls.
A persistent startup warning explains when JavaScript is disabled, blocked, or unavailable in a local-file viewer.
The mobile portrait layout retains its source, transport, mixer, and utility-panel order.

Known limitations

The selected song's stems are still decoded fully into browser PCM memory. Browser codec support remains format-dependent. The iOS Files preview may display HTML without allowing the JavaScript and audio capabilities Stem Hero requires.

Keyboard

Space plays or pauses. Home stops and returns to the beginning. Shortcuts are ignored while a control or text field has focus.

License notice

This build contains original HTML, CSS, and JavaScript with no bundled third-party runtime libraries, codecs, fonts, artwork, or songs. No project-wide open-source license has been selected yet. Users are responsible for having the right to use files they load.
