Add face design: ASCII expressions + matrix rain simulator, wait cues, fresh latency numbers
- 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) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
