💡 What

Added aria-live="polite" and aria-atomic="true" to the score element, and added a visible instruction line below the score explaining the keyboard bindings.

🎯 Why

Users were confused about how to jump since the game uses custom keyboard events ("Space" and "ArrowUp"), but provided no on-screen hints. Furthermore, screen readers wouldn't announce the dynamically updating score.

📸 Before/After

(See attached screenshot and video in verification)
The instruction text sits cleanly below the score in a semi-transparent white font to match the existing UI.

♿ Accessibility

  • Added aria-live="polite" and aria-atomic="true" to the score counter.
  • On-screen instructions now ensure all users are aware of the required controls.

- Added `aria-live="polite"` and `aria-atomic="true"` to the score
  element to announce score changes for screen readers.
- Added visible `#instructions` below the score explaining the custom
  "Space" or "Up Arrow" bindings to prevent user confusion.
- Removed invalid `venv` entry from `requirements.txt` to fix pip installs.
