Commit:   51bdc99209741bc8f600c177e68ac3be6b0f837f (version 1.1.3 in docs/CHANGELOG.md)
License:  MIT, Copyright (c) 2025 Ion Mateus (see LICENSE)

Files: game/pages/game.html -> index.html, game/scripts/index.js ->
scripts/index.js, game/styles/style.css -> styles/style.css (unchanged).
The landing page (index.html, website/), docs/ and the save.txt backup copies
were not copied.

index.html
- <title> "Document" changed to "PoliGuard".
- Removed the Tailwind Play CDN script (cdn.tailwindcss.com), the Google Fonts
  link (Inter, Orbitron) and the tailwind_config.js script. Added
  styles/tailwind.css (see below) and styles/fit.css. Text falls back to the
  system sans-serif font.
- Removed the "Return" button (it called an undefined window.redirect() and
  pointed to the project's landing page) and the "Go to home page" button on
  the game-over screen (it called an undefined goHome()). "Play new game" is
  kept.

styles/tailwind.css (new)
- Compiled with tailwindcss 3.4.17 (MIT, Tailwind Labs; license in
  LICENSE-tailwindcss.txt) from the classes used in index.html and
  scripts/index.js, using the theme from the original
  game/styles/tailwind_config.js. It replaces the Play CDN, which built the
  same CSS in the browser at runtime.

styles/fit.css (new)
- Sizes the 1000x480 game canvas to fit the frame next to the tower panel.
- Sets body text to white; the original set no text color, so the money,
  lives, score and wave numbers in the top bar were black on black.

scripts/index.js
- Mouse coordinates are converted from CSS pixels to canvas pixels
  (x canvas.width / rect.width) in the mousemove, drag, wheel, click and
  right-click handlers, so the canvas can be displayed at any size.
- Right-click (tower targeting menu) now uses the same zoom/camera conversion
  as left-click; before, it never found a tower at the default zoom.
- Starting zoom changed from 0.5 to 1, so the whole path fills the canvas at
  the start (mouse wheel zoom from 0.5 to 1.5 still works).
- Added function updateDisplay() { updateUI(); } - the upgrade and sell code
  called updateDisplay(), which was never defined, and threw an error.
- Canvas text font 'bold 16px Inter' -> 'bold 16px Inter, sans-serif'.

Line endings (CRLF) are preserved. Towers, enemies, waves, costs and all
other gameplay values are unchanged.
