Description

Accessibility logic and input changes are currently intertwined and spread across multiple systems. This issue tracks splitting and restructuring the code into focused, reviewable parts.

Tasks

• Split accessibility work into focused PRs:
  • Accessibility core (code only)
  • Input / keybind changes
• Consolidate accessibility-related logic into appropriate modules
• Avoid scattering TTS and cue logic across unrelated gameplay systems
• Review overridden bindings (e.g. Z replacing zoom)
• Ensure all new hotkeys are configurable
• Avoid hardcoded key conflicts
• Ensure keybind behavior is documented consistently

Acceptance Criteria

• Accessibility logic is centralized and easier to reason about
• Input changes are isolated and configurable
• No default keybind conflicts without justification
• PRs are small enough for focused review
