Bring the slice-1 alteration engine into the simulator so the experience
look can be tuned before hardware (operator simulator-first directive).
Python-canonical engine, thin browser renderer; Dark/Light as a live
runtime grade, Left/Right as a 5x5 grid of pre-baked authored variant
clips selected by coordinate.
Revises the machine-altered-perception design SS4.3/SS10: the Left HUD is
now baked into authored variant videos (authorial precision over the HUD)
rather than a runtime overlay, trading away near-free multilingual support.
Retires the simulator's selection-era X-ray view + endpoints.
