The Pi (hermes-bot) is flashed, upgraded and running ROS 2 Jazzy. The ST7789 works through Blinka on lgpio: pass cs=None (the kernel owns CE0), and the glass sits at y_offset=80 in the controller RAM for every rotation, since the driver rotates in software. The mounted pose needs rotation=270. hermes_face is a numpy port of the flat face from docs/face-prototype.html, with phosphor and vector styles, plus a new `sleeping` pose for "no agent connected". The renderer has no ROS or hardware imports. The tone map is a lookup table and the glow runs at half resolution, so the face reaches ~28 fps on the panel at 24% of a core (20 fps) to 40% (30 fps) with the CPU at full clock. CONTEXT.md now records the Pi, the cloud-init first-boot-only gotcha, and what is left. pi/50-cloud-init.yaml is a gitignored Wi-Fi template.
