+**Slice 2 — simulator-first alteration preview ✅ Done.** Merged to `main`
+(session 0009). Wires the alteration engine into the web simulator so the look is
+tunable by eye before any hardware, and **reconciles** the unmerged session-0007
+design with the merged session-0008 design (the Left-HUD conflict): Left is a
+**runtime overlay** (authored annotation track + per-language string tables),
+Right is a **discrete pre-baked** flow-stabilized variant, Dark/Light a **live**
+grade — superseding 0007's baked-HUD 5×5 grid. Engine: a parameterized
+`Calibration` (tuned by eye, baked into `DEFAULT_CALIBRATION`), `Restyle.variant`
+(discrete) replacing the continuous blend, and `AnalyticalOverlay.level`. Sim:
+`/api/alteration` + `/api/clips` over `simulator/clips.py`, an alteration-preview
+UI, and one neutral clip with a real flow-stabilized Right variant from the POC.
