The README described a CLI with a minimal web UI and told people to fix
charts in Yass. Rewrite it around how songtrace is used now: what it
does, its requirements up front (an NVIDIA GPU, tested on 12 GB, Docker
with the NVIDIA Container Toolkit, a Whisper server of your own, disk for
models and per-song files), a Docker quick start including writing songs
straight into a game's collection, then reviewing, editing and
rebuilding in the web UI. The command line moves near the end.
Regenerate the screenshot to show the note sheet: the screenshot script
now seeds the featured song with syllables, a chart, a pitch track and a
line break, and always scrolls to the review. The example config no
longer sets a real person as #CREATOR, and uses a reserved example host
for Whisper.
Since breaks could be moved, the sheet widened its window to show the
breaks either side of a line. Before an instrumental passage the break
sits mid-gap, sometimes 15s away, so the line's notes were crushed into
a corner of the sheet. The window now grows at most 3s past the line to
show a break; one further off is pinned to the edge, labelled with an
arrow toward where it lies, and still drags inward.
