The first real session moved on every 5 s with text only, too fast to follow.
Each step now waits for Next (Space or the window's button), counts down 3-2-1
while recording, then holds. P pauses, R redoes a step, S skips a section;
"Advance by itself" (--auto) keeps the old timed flow. Nothing records while
a step waits: each step is its own recording part.
The panel and the window show a picture of each pose (hands/rec/poses,
generated by make_poses.py from a parametric hand, MIT) and a diagram of where
to hold the hands and how far out. prompts.jsonl gains ready, wait and redo
events; session.json gains mode.

A head-locked SteamVR overlay for the hand recorder (hands/rec/DESIGN.md):
1.2 m ahead, 12 degrees up, 36 degrees wide, drawn with stb_truetype
into three shared DMA-BUFs as ft-gazepanel does. It shows the title,
step, wrapped instruction, note, countdown, hand chips, near/far bar
and a "Paused" cover, driven over @ft_handpanel.
It also places the touch target, a 2 cm dot in its own overlay fixed
in the room where the head was at the first command for that point,
and logs head and controller poses to poses.jsonl at 250 Hz from a
thread of its own. Both threads take one lock around OpenVR calls.
--no-vr prints each picture's state to stdout (and --dump writes the
pictures), for testing without a headset. hands/rec/build.sh builds it
in the dev container.
