Checked-in subset: velocity layers v4, v8, v12, and v16 at the available Salamander strike anchors, plus all 88 release samples. The strike anchors are A, C, Dsharp, and Fsharp for octaves 1-7, plus A0, A7, and C8. The app derives strike MIDI values and velocity layers from filenames in piano-samples.ts; release sample rel1 maps to A0 and rel88 maps to C8.

Repro notes: start from the matching OGG files in the source packages (~88 kbps Vorbis, 48 kHz stereo) and transcode each selected sample to AAC/M4A at 96 kbps (ffmpeg -i <src>.ogg -c:a aac -b:a 96k -movflags +faststart <dest>.m4a) without renaming the note/velocity or release stem. Strike samples longer than 12 seconds are faded out from 10 s to 12 s and cut there (-af afade=t=out:st=10:d=2 -t 12); the sampler's own gain envelope masks the shortened tail. Replace # with sharp in filenames for URL compatibility. Expected output filenames include <note>v<layer>.m4a, for example C4v16.m4a, and rel<index>.m4a, for example rel40.m4a.
