Changes made for this site (original: https://github.com/Douile/tower-of-hanoi @ 492a3f0a43fa25b65c10bf42a3c24b926fd10c7a)
- Copied only runtime files (index.html, tower_of_hanoi.js, the five icons in use) plus LICENSE.
  The icons are Feather icons (https://feathericons.com/, credited in the original README);
  Feather's MIT license is included as assets/FEATHER-LICENSE.txt.
- index.html now loads the unminified tower_of_hanoi.js instead of the Babel-minified
  tower_of_hanoi.min.js (not copied).
- index.html: removed the "View on github" link (it navigated away from the game); the
  "Made by Douile" credit is kept. Added an on-screen restart button (assets/restart.svg,
  which was already in the repo but unused). The overlay layer no longer blocks clicks on the canvas.
- tower_of_hanoi.js (additions are marked "Added for this site"):
  - Click or tap a tower to pick up its top ring or drop the held ring there (the original
    was keyboard-only); it reuses the original pick-up/drop logic.
  - The canvas now matches its on-screen size (and resizes with the window) instead of a fixed
    4000x4000 bitmap stretched to the frame; the move counter font scales with the canvas.
  - The restart button calls the same reset as the R key.
Puzzle rules, keyboard controls and the auto-solver are unchanged.
