- sim/face/index.html: browser simulator of the 800x800 round panel with
six states (idle/listening/pensive/effort/speaking/error), state-driven
rain density, blink/talk/thought animations, idle clock
- effort state gets hard-required wait cues: orbiting bezel arc, elapsed
counter, max rain (Tatlock turns run 10-25s)
- rain driven by setInterval, not rAF: renders under the screenshot
tool's --virtual-time-budget and mirrors LVGL lv_timer
- architecture.md: Face design contract (state table, protocol mapping,
LVGL port notes) + latency table updated to GPU-era benchmarks
(Steward ~6s warm, full flow 11-25s; old CPU-era figures retired)
