Changes made for this site (original: https://github.com/thomaspark/flexboxfroggy @ 9a6feab850a56cbe9ad90f3afcc95e88335bbec8)
Original game by Thomas Park, MIT License (see LICENSE). Renamed for this site to "Flexbox Lily Pond".

- Copied runtime files only: index.html, favicon.ico, css/style.css, js/*.js, images/*.svg (frogs and lilypads),
  plus LICENSE. Not copied: images/games/ (promo images for the author's commercial games), images/screenshot.png,
  ads.txt, CNAME, _config.yml, package files.
- Libraries moved from node_modules/ to lib/: jQuery 3.5.1 (MIT, lib/jquery-LICENSE.txt) and animate.css
  (MIT, license in the file header). Both unchanged.
- index.html: removed Google AdSense (script, ad slot and meta tag), Google Analytics, Open Graph/Twitter/Facebook
  meta tags, the promo tiles and text links to the author's commercial game site, and its YouTube/Twitter links.
- index.html: replaced the Google Fonts link with fonts/fonts.css (local PT Sans, Fredoka One and Source Code Pro,
  all SIL OFL 1.1; license texts in fonts/).
- Renamed the game in the page title, heading and footer. The footer now reads "Flexbox Lily Pond is based on an
  open-source game by Thomas Park (MIT License)" with links to the author's GitHub profile and the source repository.
- Language: the game shipped 50+ translations inline. We kept English only: js/levels.js, js/docs.js and
  js/messages.js were regenerated with only the "en" strings (re-serialized as JSON; the level data, boards and
  styles are unchanged), the language picker was removed from Settings, and js/game.js now always uses English
  instead of reading the language from the URL hash or the browser.
- js/levels.js: the first level's welcome sentence names the new title, and the final "You win" text no longer
  includes the paragraph linking to the author's other commercial games.
- js/game.js: removed the code that inserted Twitter share/follow buttons on hash change.
No level, answer check or game rule was changed.
