Changes made for this site (original: PixelCraft, https://github.com/gitstq/PixelCraft @ 0cf9f802b5fab1dda7d7663b7f54a4b440663543)
Copied index.html, app.js, styles.css and the original LICENSE. Changes are marked "[site patch]" in the code.

index.html
- Renamed for this site: page title and header now read "Pixel Sketch Studio" (was "PixelCraft").
- The "GameBoy" palette button is labelled "Retro Green" (a third-party product name; the colors are unchanged).
- <html lang> changed from "zh-CN" to "en" (the interface text is English).

app.js (bug fixes)
- The view now opens fitted to the available space. Originally it opened at a fixed 4x zoom of a 512 px canvas,
  so only the blank middle of the drawing area was visible.
- The on-screen pixel size is recalculated from the canvas dimensions, and the view is re-fitted after a
  canvas size change (large canvases no longer open far bigger than the screen; small ones are no longer tiny).
- Grid lines are mid-gray at 45% opacity (were white at 15%, which could not be seen on the white canvas).
- Adding or duplicating a frame now redraws the editor immediately (before, the new frame did not appear
  until the next brush stroke, while strokes already went to the hidden new frame).
- Deleting a frame now records an undo step; a duplicate initial undo step was removed so Undo is not
  enabled on a fresh canvas.

styles.css
- On screens 768 px wide or less, the Colors / Palettes / Brush panel is shown as a scrollable strip under the
  canvas instead of being hidden (it was display:none, leaving phones with no way to pick a color).

- 2026-11-04: Display title text changed from "Pixel Sketch Studio" to "PixelCraft" (1 file(s)). Game logic unchanged.
