Hold both buttons at power-on to enter a self-contained jog screen: the joystick
spins the stepper CW/CCW (speed by deflection), with an on-screen direction
needle + RGB LED feedback. Runs in its own loop; power-cycle to return to normal.
- app.py: _jog_loop drawn entirely in the overlay group (cover + labels + needle);
Pendulum.spin() does a free half-step either way; _jog set when A+B held in init;
run() branches to it before the normal loop.
- boot.py: editor mode is now "A alone" (A pressed, B not). A+B stays in appliance
mode, so the jog chord doesn't also flip the drive writable.

Firmware (pico-cp/): the Pico now owns its filesystem by default (boot.py), so it can save the
practice log and write editor-pushed set lists; the drive is read-only to the computer, which also
protects the firmware. Hold button A at power-on for editor mode (drive writable; universal drag).
- Replaced the on-screen touch buttons with an on-device PRACTICE LOG (time · BPM · duration ·
track), newest-first, persisted to /history.json next to programs.json. Plays < 5s aren't logged;
tap a row twice to delete it. Real timestamps once the editor syncs the clock.
- USB-MIDI SysEx receiver: clock-set (0x01 -> RTC) and program-push (0x10 -> write programs.json,
reload, ACK/NAK). disable autoreload so our own writes never self-restart.
- Fixed swing: the parser was discarding the 's' flag, so /2s never swung. Now the scheduler uses a
per-step duration with long-short (2:1, SWING_RATIO 2/3) pairs on even subdivisions, matching the
web engine. Verified: ride:4/2s -> 266/133ms vs straight 200/200.
Editor (editor.html): requestMIDIAccess({sysex:true}); Save to device now pushes programs.json as
SysEx to the device (+ clock sync), waits for ACK, shows "Saved ✓", and falls back to downloading the
file (drag onto the drive in editor mode) when no device answers. Heartbeat also keeps the clock synced.
Web MIDI works in Chromium AND Firefox; the drag fallback covers any browser/OS incl. Safari.
Docs (pico-cp/README, info-kit, README) updated for the two modes, push programming, and the log.

If the device isn't seen as a MIDI input (USB endpoint pressure from drive+serial+HID+MIDI),
boot.py disables the unused HID interface and enables usb_midi — copy it on and power-cycle.
Bundled into pm_k1_circuitpy.zip; documented in the README.
