# HyperTwist Phase I-E comfort, accessibility, and performance hardening preparation packet

## Goal

Close the initial first-party immersive scaffold with a bounded hardening layer
 that makes the scenic training environment safer and more dependable for
 regular use.

## Scope

- comfort-safe transition rules
- immersive accessibility and legibility review posture
- bounded performance-budget contracts
- reduced-effects and compatibility-safe fallback modes

## Non-goals

- engine-global scalability ownership
- platform-global accessibility shell ownership
- generic graphics-settings menu ownership
- broad camera, locomotion, or renderer-pipeline ownership

## Planned code surfaces

- extend the immersive environment reference bundle with hardening ids and
  contracts
- expose runtime accessors for the new hardening surfaces
- add focused automation proving transition safety, accessibility-legibility,
  performance budgets, and fallback posture
