Me Here ec29fb7284 pm-ui: notation refinement — shared stems + ledger lines
Gather notes per time-column across lanes; draw one shared stem per voice (hands
up / feet down) spanning the chord, so snare+hat on a beat share an up-stem. Ledger
lines for notes above/below the staff (hi-hat on its ledger line, crash higher).
Stems always clear the highest/lowest notehead; beams grouped per beat.

Rust port — track-format crate (Stage 1)

Pure parse/serialize codec for the track DSL, validated against the shared golden vectors (tests/fixtures/track-format.json) — the third implementation alongside engine.js and app.py. See docs/rust-port.md for the staged plan.

All tooling runs in a container (per the develop-in-container rule):

./rust/run.sh            # cargo test — runs the conformance + idempotency suite
./rust/run.sh cargo build
./rust/run.sh bash       # interactive shell in the crate
